Welcome to Me and my child website, previously called Bubbahood

Pregnancy Tracker Week 1

Mother

First, a note about timing: Your pregnancy is dated from the first day of your last menstrual period. So, for the purpose of the calculation made by your healthcare professional, you are considered pregnant about 2 weeks before you actually conceived. During week 1, your normal menstrual period occurs.

Pregnancy Tracker Week 2

Mother

During this week, your body prepares to ovulate. Ovulation takes place when an egg is released from one of the ovaries. Once an egg is released from an ovary, it must be fertilised by a sperm within 12 to 24 hours for conception to occur. (If one fertilised egg splits or if multiple eggs are fertilised, you could have twins, triplets, or more!) The meeting of sperm and egg will take place near the end of this week.

Pregnancy Tracker Week 3

Mother

The united egg and sperm begins as a single cell, which divides very quickly and travels along the fallopian tube to the uterus (womb). Once in the womb, it burrows itself into the thick lining, where it will continue to grow. With no noticeable physical changes at this point, you probably won’t yet be aware that you have conceived.

Baby

The fertilized egg, called an embryo, beginning to grow inside you is tiny. By the time it reaches your uterus, it is a little ball of cells.

Pregnancy Tracker Week 4

Mother

The missed period that you were expecting at the end of this week will probably be the first major clue that you are pregnant. Tingling, tender, or swollen breasts may be another early sign that you are pregnant.

Baby

Baby’s cells continue to multiply, and placental tissue grows. At this point, though, the cluster of cells is microscopically small—no bigger than a poppy seed. Nevertheless, 3 different cell layers are developing that will later form your baby’s body. The ectoderm (outer layer) will produce your baby’s brain and nervous system, the eye lenses, tooth enamel, skin, hair and nails. The mesoderm (middle layer) will develop into the skeleton, heart, blood vessels, and muscles. The endoderm (inner layer) will become the lungs and digestive systems.

Pregnancy Tracker Week 5

Mother

Your breasts will begin to enlarge and may become tender. You may need to urinate more often than usual because of your expanding uterus. It is also common to feel noticeably more tired than usual—after all, your body is working hard to create a new human being!

Baby

This week, your baby is around 2mm long and looks more like a small tadpole. Your baby’s heart starts to beat, and the spinal cord, brain, arms, legs, liver and kidneys are starting to form.

Pregnancy Tracker Week 6

Mother

Some women may start to experience nausea and/or vomiting at this stage — commonly known as morning sickness. About 75% of pregnant women suffer from morning sickness, which may actually occur at any time during the day. At this time you may not notice much change externally. If you have had morning sickness and have not been eating as much as usual, you may have lost some weight.

Baby

Your baby now measures about 5-6 mm in length -the size of a lentil. Baby’s head is larger than the rest of their body, but their arm and leg buds are starting to lengthen. The facial features are forming and your baby’s tiny heart is beating at approximately 150 beats per minute. By now your baby is covered with a thin layer of clear skin.

Pregnancy Tracker Week 7

Mother

Although you may be starting to feel pregnant and notice your clothes are getting a little tighter, most people still won’t be aware that you are unless you tell them. You may also notice that you are more emotional these days—the many hormones circulating through your body, make mood swings almost inevitable.

Baby

Your baby is growing quickly, about 1cm long -the size of a blueberry. Their brain is forming about 100 cells per minute. Their mouth and tongue are forming, and also their arm and leg buds are now shaped like short paddles. Their kidneys are at a stage where they are ready to start waste management.

Pregnancy Tracker Week 8

Mother

Your pregnancy is slowly changing your figure. You may notice your waistline expanding.

Baby

Your baby now called a fetus is about 1.6cm in length. Despite this small size, their central nervous system and major organs are beginning to function. Their features are starting to take shape and they are now starting to look like a miniature human being.

Pregnancy Tracker Week 9

Mother

You may experience a roller coaster of emotions at this time. This is largely due to hormonal changes taking place in your body. Around this time you may also notice that you are more prone to gas, heartburn, and constipation. You can thank your hormones for these normal, if somewhat unpleasant, changes.

Baby

By now your baby measures about 2.3 cm long and weighs under 2g. Their arms are longer and bend at the elbows. Their fingers and toes are also now better defined. Muscles are starting to form and their internal organs continue to develop. Even though gender cannot be identified by ultrasound yet, your baby’s genitals have begun to form.

Pregnancy Tracker Week 10

Mother

Even though your clothes may not be fitting as well, you probably don’t need maternity clothes just yet. Every pregnancy belly is different, some show as early as the first trimester, others stay flat well into the second trimester. If you are slender to start with or had a baby before, you may show early. Hormones may also affect your interest in sexual activity either an increased or a diminished interest is perfectly normal.

Baby

Your baby now is about 3 cm in length and weighs about 4 g. The head is almost half the length of their body. Bones and teeth are forming, and their ears are starting to develop on the sides of the head. The heart, lungs, liver, kidneys, brain and intestines are fully formed and functional.

Pregnancy Tracker Week 11

Mother

Your uterus has now risen above your pelvis and is a little bigger than a grapefruit. During an external examination, your healthcare professional may be able to feel it. A dark vertical line may also start appearing across your belly.

Baby

Your baby is just over 5cm long and weighs about 9 g. The head is now one-third of their body and the torso is lengthening. Nail beds are starting to form on individual fingers and toes, and tiny hair follicles are starting to appear.

Pregnancy Tracker Week 12

Mother

You may notice weight gain in your abdomen and breasts with your clothes feeling tighter. You are probably starting to feel the best you have felt since becoming pregnant. At about this time, morning sickness may start to diminish for a lot of women. The risk of miscarriage has by now declined considerably, so you may be ready to share your good news with the world.

Baby

Your baby’s length is now approximately 6 cm and weights about 15g. All of the major organs, muscles, limbs and bones have finished forming—now they just need to mature. Although it is still too early to feel any movements, your baby is already moving around a fair bit.

Pregnancy Tracker Week 13

Mother

By now, your regular clothing may be feeling a bit snug—and it’s time for the transition to looser garments! Your breasts have increased in size and weight. The areola, which surrounds the nipple, is growing larger and darker, and the veins in your breasts are becoming more visible.

Baby

Your baby is now about 7-8 cm in length and weighs about 23 g. Your baby’s ovaries or testes are fully developed, and their genitals are forming outside their body. Your baby’s unique fingerprints are already in place and their vocal cords will start to develop.

Pregnancy Tracker Week 14

Mother

As your uterus expands to make room for your baby, you will start to notice a definite tummy bulge. Now or soon you will need new clothing to fit your growing waist. And for the first time in a long time, you may feel the need to urinate less often.

Baby

Your baby is now about 9cm long and weighs about 43 g. Their neck is longer, and the head now sits up from the chest. They are covered in lanugo, a fine downy hair that keeps them warm. They are also growing hair on their head along with eyebrows. They can now grasp, frown and may even suck their thumb.

Pregnancy Tracker Week 15

Mother

Your pregnancy may now be evident to others if you wear form-fitting clothing or maternity clothes. However, this varies from woman to woman and depends on your own body shape and build. With your circulatory system moving more blood than usual through your veins and arteries, you may develop varicose veins—blueish veins that are a bit swollen and can cause discomfort. Don’t be surprised if you notice increased vaginal discharge. As long as it is white and watery-looking, the discharge is normal.

Baby

Your baby is now about 11cm long and weighs about 85 g. Their legs are growing longer than their arms and all joints and limbs can move. The fingernails are also fully formed. Your baby will start to hear and develop hiccups, but you won’t be able to hear it as their lungs are filled with fluid rather than air. If the external genitals are developed enough, the gender of your baby can be determined by ultrasound.

Pregnancy Tracker Week 16

Mother

Around this time, you will start to notice that the symptoms that you had early in the pregnancy are starting to ease up. You might find that your energy level is picking up. It’s also normal to feel some apprehension about what lies ahead as motherhood approaches.

Baby

Your baby is now about 11-13 cm long and weighs about 85-140 g. All of baby’s muscles are in place and getting stronger. Eyebrows and eyelashes have appeared, and the eyes are able to make small side to side movements and detect some light even though the eyelids are still closed. Around now, your baby’s hands can hold onto each other and grab onto the umbilical cord.

Pregnancy Tracker Week 17

Mother

By now, anyone who gives you a hug will feel the bulge in your lower abdomen. During the second trimester, most women gain between 5 to 6 kg. This week you may have one of the most exciting experiences of your pregnancy—feeling the baby move for the first time. Many women describe the feeling as “fluttering”.

Baby

Your baby is now about 13cm long and weighs about 140 g. The body grows bigger, so that the head is now more proportional to their body. Their sucking and swallowing reflex continues to develop. During this week and the weeks that follow, your baby will start to accumulate fat.

Pregnancy Tracker Week 18

Mother

Around this time, you might start to experience lower back pain. This can be common in pregnancy as the joints of your pelvis expands to prepare for the delivery of your baby and your growing abdomen throws your body off balance.

Baby

Your baby is now about 14cm long and weighs about 190 g. A mid-pregnancy ultrasound scan is often done sometime in the second trimester to assess growth and development. During this scan you might see your baby kick, flex, roll or even suck their thumb.

Pregnancy Tracker Week 19

Mother

At this point, you may feel your baby moving and kicking. Although your baby moves around quite a bit, you probably won’t be feeling it consistently until later in your pregnancy. Around now, you may notice your nails and hair are growing faster than ever before.

Baby

By now, your baby is about 15cm long and weighs about 225 g. This week sensory development is taking place as each of the senses (taste, smell, hearing, sight and touch) are developing in their specific areas of the brain.

Pregnancy Tracker Week 20

Mother

By now you are probably feeling the many turns and twists of your baby as they make your uterus into their own personal “exercise” room. Their growth is also causing your abdominal muscles to stretch and be pushed apart. You may also feel a dull ache in your lower abdomen as the ligaments supporting your uterus stretch. It’s also not unusual to feel light-headed when you move quickly from a sitting to standing position.

Baby

At the midpoint of your pregnancy, baby measures about 16 cm long and weighs about 280 g. Their developing skin will start to be covered by vernix, a white fatty substance that helps to protect their skin from the surrounding amniotic fluid.

Pregnancy Tracker Week 21

Mother

You can’t hide it any more—even strangers can tell that you are expecting! You may sometimes suffer from swollen ankles and feet, and occasionally the hands and face. As your baby grows and develops, you may also feel hungrier than before and crave for certain foods.

Baby

Your baby is now about 17cm long and weighs about 310 g. They are swallowing amniotic fluid each day and their digestive system is starting to function at a basic level. Their arms are finally in proportion to their legs. With their developing senses, they are more aware of your voice, as well as noise levels in your surroundings.

Pregnancy Tracker Week 22

Mother

Although you definitely have a sizable pregnancy “bump”. You’re probably feeling fine, though maybe a little more absentminded than usual. Some minor discomforts may include heartburns, sensitive gums that bleed when you brush and leg cramps.

Baby

Your baby is now about 20cm long and weighs about 450 g. Their body is getting larger every day. They now have well-developed lips and their tooth buds are starting to appear below the gum line. And since their taste buds are now developed, they can experience the flavours that cross through the placenta and the amniotic fluid they are swallowing.

Pregnancy Tracker Week 23

Mother

At this point, your size and your baby’s size are steadily progressing. Your health care professional will continue monitoring you to make sure this is so. You may feel more pushes against your belly as your baby starts moving more. Don’t be surprised if you experience clumsiness or are a little more forgetful—it’s all normal.

Baby

By this week your baby has reached over 500 g. Although they are heavier than previous week, their skin is still saggy in appearance. Their hearing is established and they can hear your heartbeat and voice. Their lungs are also forming, in preparation for breathing.

Pregnancy Tracker Week 24

Mother

As baby’s arrival draws closer, it’s common to experience both anxiety and excitement about the future. Other changes you might notice around this time include pigment changes in your skin. Stretchmarks may appear across your abdomen, hips and breasts.

Baby

Your baby is now about 22cm long and weighs about 680 g, but they still have a lot of growing to do. Their face is almost fully formed and complete with a full set of eyelashes and eyebrows. They have actually developed enough to have a chance of surviving outside your body with intensive care if it is necessary to deliver prematurely.

Pregnancy Tracker Week 25

Mother

A glance at your side view in the mirror reveals that your uterus has grown quite a bit in a few weeks. Your uterus is now about the size of a basketball. Your breasts have also grown substantially. What new symptoms might you be noticing? Leg cramps are common at night in the second trimester. Or perhaps you’re feeling a bit itchy—the natural result of your skin stretching.

Baby

Baby now weighs about 660 g as they continues to grow. Their lungs are not quite ready for full function yet and need some more time to develop. They are making breathing movements but no air is filling their lungs yet.

Pregnancy Tracker Week 26

Mother

Since your baby is now almost 36 cm long, you’re more likely to feel the full effect of their kicks. With your uterus and baby growing larger, you are now more prone to backaches, mild swelling in your ankles, and leg cramps. You might also experience “Braxton Hicks” contractions— tightening of the muscles of your uterus that occur irregularly as your body practices for labor.

Baby

Your baby continues to fill out, now weighing about 760 g. They will really be piling on the grams in the weeks to come. They are able to inhale and exhale and their eyes are starting to open and close.

Pregnancy Tracker Week 27

Mother

As your baby is growing quickly in this phase, ensure you maintain a nutritious diet. As you near the end of the second trimester, it’s common to feel somewhat stressed or restless—your body has been undergoing a major construction project, and you know that you still have one stage to go. Relax, and take it easy.

Baby

This week, your baby will likely be about 875 g as their skin changes from being transparent to opaque. You will notice that your baby now has a regular sleeping and waking cycle.

Pregnancy Tracker Week 28

Mother

By now, you might have gained about 5 kg during this trimester. You may have also noticed a change in the quantity of food that you consume. At your antenatal check, your doctor or midwife will feel your abdomen – your uterus will now be well above your navel.

Baby

In the past 4 weeks, your baby has doubled their weight, to about 1 kg. They are working on forming their fat layers and their fingernails are now formed.

Pregnancy Tracker Week 29

Mother

The extra weight you’re carrying and the expected interruptions in your sleep are probably starting to make you feel a bit more tired. You’re also less nimble—and that’s not surprising, because your center of gravity has changed and you probably can’t even see the tips of your toes when standing upright. Slow down a little now—things will be quite busy soon enough!

Baby

Your baby now weighs a little over 1 kg and measures almost 38 cm in length. Their fat stores under their skin contributes to that weight. Your baby can hear well now and reacts to sounds from outside your womb.

Pregnancy Tracker Week 30

Mother

You may already feel quite large, even though you still have about 10 weeks to go before delivery. The average healthy gain during pregnancy is about 13.5 kg. The uterus, baby, placenta, and amniotic fluid will account for about ½ of your weight gain. The other ½ goes to your breasts, body fluids, blood, and maternal nutrient stores.

Baby

Baby now weighs almost 1.4 kg. The volume of amniotic fluid will decrease as they grow and gain weight rapidly during the next few weeks. Their brain continues to grow and make connections between its cells over the next several weeks.

Pregnancy Tracker Week 31

Mother

At this stage, your uterus is approximately 28 cm from the top of your pubic bone and fill a large part of your abdomen. You may start to feel breathless at times because the baby is pushing up against your lungs.

Baby

Your baby now weighs around 1.5 kg and measures about 41 cm in length. They are able to perceive signals from all 5 senses. Your baby’s organs are still maturing and they are starting to pass water from their bladder.

Pregnancy Tracker Week 32

Mother

One of the most common symptoms around this time is swelling in your ankles and feet due to the increase in body fluids. You may find that the swelling disappears overnight or after several hours of lying down.

Baby

Your baby now weighs about 1.7 kg and is about 42 cm long. They are probably spending most of their time asleep. Their lungs will continue to mature over the next few weeks. During this time they are inhaling amniotic fluid to exercise their lungs and practice their breathing.

Pregnancy Tracker Week 33

Mother

Your amniotic fluid levels are peaking right about now. Pregnant women can carry the fetus in a number of ways—high, low, wider, smaller, more compact, etc. All of these contours are normal they depend on your baby’s size and position as well as your own height and build.

Baby

This week your baby weighs about 2 kg. Their length is now about 44 cm. Their skull has not completely formed, however the bones in the other parts of the body are hardening.

Pregnancy Tracker Week 34

Mother

Sometime in the next few weeks, you may notice that your belly is a bit lower. This phenomenon, known as “dropping” or “lightening”, occurs when the head of the baby enters the pelvic cavity. You may enjoy the extra room in your upper abdomen, but notice a little more pressure in your pelvis and bladder.

Baby

Your baby now weighs about 2.2 kg and measures over 45 cm in length. They are nearly out of room in your uterus and you’ll notice a change in the way they bump against you. With no space for more amniotic fluid to cushion your baby’s movements, you may feel discomfort from their kicks and blows. This is a good time to start talking to your baby as in the next week or so their hearing will be fully developed.

Pregnancy Tracker Week 35

Mother

By now you may have gained between 11 to 13 kg. Your health care professional should be able to tell by now how your baby is positioned—upside down, with his head ready to come out first. This is also a time when your emotions seem to get the best of you—which is perfectly normal as you approach delivery. The pressure on your bladder may make you run to the bathroom more often than usual.

Baby

Your baby now weighs about 2.4 kg and is 45 cm in length, making it a little bit of a squeeze for them to fit in your body along with your other organs. Their brain is developing at a rapid pace but their skull is still soft allowing for the squeeze through the birth canal. This week your little one should also have a fully developed pair of kidneys.

Pregnancy Tracker Week 36

Mother

Good news! By the end of this week, your pregnancy will be full-term. Your baby’s head may begin to ease and nestle into your pelvis ready for birth. You will find breathing is easier once baby’s head is engaged as pressure is no longer against your lungs.

Baby

Your baby now weighs about 2.7 kg and measures 45 cm in length. Their digestive system is functioning. During these final weeks in your womb, they will spend a fair amount of time practicing their sucking reflex on their thumbs.

Pregnancy Tracker Week 37

Mother

Good news! This week, your pregnancy will be full-term. Towards the end of your pregnancy, you may notice a yellowish fluid coming out of your nipples. Your breasts are making a “test batch” of colostrum—the first breast milk that your body will produce for your newborn. At this week’s checkup, your doctor may check for effacement (how much your cervix has softened and thinned in preparation for labour) and dilation (how much the cervix is open). In addition, your doctor will check the position of your baby and how far down the birth canal your baby has descended. This exam will serve as a benchmark in the coming weeks so that your doctor can monitor your progress.

Baby

Your baby is now considered full term. This week, your baby measures about 50 cm in length and weighs about 2.8 kg. Although ready for life outside the womb, your baby is still growing and gaining about 500 g each week. If they are like most babies, their head is now pointed down into your pelvis. Your baby’s gut now contains meconium-a blackish waste that contains downy lanugo and white fatty vernix that covered your baby earlier in pregnancy. These coatings, along with other secretions, will become your baby’s first poo after birth.

Pregnancy Tracker Week 38

Mother

You and your partner may be amused to detect—sometimes through the movement of your clothing—the squirming that is occurring in your crowded womb right now. You may have some symptoms that are less enjoyable, such as backache or leg cramps. Talk to your doctor if they are really troublesome, but otherwise take comfort in the fact that the finish line is in sight.

Baby

Your baby now measures about 51 cm long and weighs just over 3 kg. Their organ systems are fully developed and in place but their lungs will continue to produce more surfactant to prevent the air sacs from sticking to each other when breathing. Even as they meet the outside world, your baby will take some time to establish a normal breathing pattern.

Pregnancy Tracker Week 39

Mother

You probably won’t get much bigger now as your baby’s growth slows down. Many women spend these last days of pregnancy organising and cleaning around the house. Your desire to “nest” could be a response to the increased adrenaline coursing through your very pregnant body.

Baby

Your baby has now reached a length of about 51 cm and weighs around 3.4 kg. The healthy weight range for newborns is between 2.5 and 3.8 kg. All of their organ systems are developed and ready to go. Now they just need to decide when their birthday will be!

Pregnancy Tracker Week 40

Mother

Congratulations! You’ve reached the end of your pregnancy. Most women will go into labour one or two weeks either side of the due date. If your baby shows no sign of making an appearance, your mind may naturally turn to thinking about possible ways to hasten the process. Patience may be the best counsel right now.

Baby

The average baby is about 51cm long and weighs about 3.3 kg, but your baby may check in smaller or bigger than that. The fatty white vernix covering their outer layer of skin continues to shed. They recognise your voice —and it won’t be long before you hear theirs.

Pregnancy Tracker Week 41-42

Mother

If you are reading this milestone, you’re probably at least a little unhappy. Most expectant mothers aren’t pleased when the baby is overdue. Keep in mind that maybe your baby isn’t off schedule—after all, a due date is just an estimate. Only 2% of women are truly over their due dates. Your healthcare professional will monitor you closely.

Baby

Since your baby has no idea which day it is, they are just as content as they were last week in your womb! Further, since studies show that about 70% of apparent “post-term” pregnancies are really not post-term (they are instead the result of a miscalculation of the due date), chances are that their development is right on schedule.
