Prenatal Care Calendar

Prenatal Care Calendar

Preparation is the key to an enjoyable pregnancy. At Westside, we work with you on a carefully coordinated plan that ensures a stress-free process for both mother and baby. We break the months of your pregnancy into a series of visits with your healthcare team so that you know about testing, ultrasounds, exams, and more ahead of time.

First Trimester

Weeks 1 and 2

Since your due date is calculated from the first day of your last period, you are not actually pregnant in what we consider weeks one and two of pregnancy. During this time, your body is simply gearing up for ovulation and preparing for fertilization.

Week 3

Conception has occurred! As sperm meets the egg, fertilization occurs and your baby-to-be takes form as a group of cells.

Week 4

The aforementioned group of cells splits into two parts. One half is the embryo, your future son or daughter! The other half forms the placenta. During this week, specialized parts of your baby’s body begin to develop as well.

Week 5

Your baby’s heart and circulatory system are developing. Your pregnancy hormone levels are now high enough to confirm your good news with a home pregnancy test.

Week 6

During week six, your baby’s head and face is taking shape. You may be experiencing pregnancy symptoms, including frequent trips to the ladies room.

Week 7

Your baby now has kidneys, and tiny arms and legs are starting to develop. You may start to notice that your breasts are growing and even achy at times.

Week 8

Your baby is growing rapidly, and now has a heart rate of 150 beats per minute! As the little one starts moving in the womb, morning sickness (which can strike at any time of day) may occur.

Week 9

Week nine marks the beginning of the fetal period, meaning your baby is no longer considered an embryo at this point. As muscle starts to form, you may be fatigued throughout the day.

Week 10

Your baby is building bones this week, and tiny teeth are even developing under the gums. If you are experiencing constipation, try upping your fiber intake.

Week 11

Fingers and toes have arrived! While only about the size of a lime, your baby is beginning to look like a tiny human. With the end of the first trimester in sight, you may start to feel more like yourself again.

Week 12

Your baby has doubled in size over the last few weeks! If you have not already heard your baby’s heart beat, you may have that opportunity at your next appointment. During week 12, baby’s digestive system is starting to function as well.

Week 13

Your baby is now about the size of a peach! Vocal cords are developing and tiny intestines are taking shape inside your baby’s body.

Second Trimester

Week 14

Your baby may be sprouting hair on his or her head, eyebrows, and body. Mom’s pregnancy symptoms should be easing up with the beginning of the second trimester.

Week 15

Your bump is becoming more and more noticeable as your baby grows rapidly. Though you may not feel movement, your baby is kicking and even flexing his or her elbows inside the womb.

Week 16

During week 16, your baby is beginning to see and hear. His or her eyes are making tiny movements, and your voice can even be recognized.

Week 17

Your baby now has his or her very own fingerprint. Little one is passing the time learning how to suck and swallow.

Week 18

At week 18, your baby is about the size of a sweet potato. The nervous system is rapidly developing, and he or she is beginning to yawn.

Week 19

Your baby’s skin has developed a protective coating, and he or she is getting more and more coordinated each day.

Week 20

This is an exciting week! If you plan to find out the gender of your baby, a routine ultrasound should give you the answer.

Week 21

At week 21, your baby has taste buds and is swallowing a small amount of amniotic fluid each day. Your diet can alter the taste of this fluid.

Week 22

Week 22 brings eyelashes and eyebrows to your baby’s face. He or she is also developing better grip, vision and hearing!

Week 23

Baby is gearing up for a period of rapid weight gain. Over the next four weeks, his or her weight will double.

Week 24

At week 24, your baby’s facial features are formed, and can be seen through an ultrasound image. Mom might notice that the belly button is starting to pop out.

Week 25

This week is all about your baby’s ability to breathe. His or her lungs are developing and nostrils start to open.

Week 26

Baby’s eyes have opened and his or her brain-wave activity is kicking in. At this point, your little one weighs about two pounds.

Week 27

Your baby can now recognize your voice, and possible the voice of your partner as well! With more taste buds than ever, he or she will respond to different types of foods by hiccuping.

Third Trimester

Week 28

At week 28, you baby is able to blink and even having dreams. At almost 16 inches long, he or she is about the size of a cucumber.

Week 29

Things are getting tight in the womb, so you will feel more and more kicks and jabs from your little one. He or she is gaining weight rapidly.

Week 30

As your baby’s brain grows rapidly, he or she is also developing red blood cells, and the ability to thrive outside the womb.

Week 31

At week 31, all five senses are present. Your baby may be sucking his or her thumb or pedaling those little feet.

Week 32

At almost four pounds, your baby is now practicing survival skills such as sucking and breathing. Your body is gearing up for labor, and you may experience some Braxton Hicks contractions.

Week 33

At week 33, your baby has his or her own immune system and can fend off germs after birth. Mom might be feeling exceptionally tired as baby is gaining half a pound each week.

Week 34

Your baby is now the size of a honeydew melon, weighing in at around five pounds. If it’s a boy, the baby’s testicles descend this week.

Week 35

At week 35, baby’s brain continues to grow, but his or her skull remains soft. This helps your little one make way through the birth canal.

Week 36

Your baby’s growth will slow down at this point. Many systems are fully developed, but his or her digestive system is still developing, and will continue through the first year of life.

Week 37

Congratulations! You have reached what most doctors consider a full-term pregnancy. Your baby is turning and preparing for birth.

Week 38

At week 38, your baby produces surfactant, a substance to help him or her breathe. Mom produces colostrum, the precursor to breast milk.

Week 39

At 39 weeks, your baby probably weights 7 or 8 pounds, the size of a Swiss chard. You may notice signs of labor.

Week 40

Week 40 is the official end of your pregnancy. Your baby might still be hanging out in the womb, but rest assured, soon he or she will be in your arms.

Week 41

Still pregnant? Not to worry, many babies are overdue. In fact, your baby may not be overdue at all, as most due dates are a few days off.

Week 42

Fewer than five percent of babies are born on their due date. If your baby is truly overdue, your heath care provider will monitor the remainder of your pregnancy closely. Try to relax…the end is near!
