Pregnancy Week 15

Woman who is 15 weeks pregnant

You are one week closer to meeting your bundle of joy! Read more about what you can expect this week.

Pregnancy Week 15: What changes are occurring with your body?

The average weight gain at this point in your pregnancy is about 5 pounds (2.27 kilograms). You may have gained a little more or a little less, which is completely normal. However, if it is significantly more or less, your doctor may want to discuss your diet at your next prenatal appointment.

Changes in the shape of your abdomen may or may not be noticeable to others. You may be able to feel the top of your uterus four to five inches (10-12 centimeters) under your belly button.*

Pregnancy Week 15: How big is your baby?

By the end of this week, your baby will be 4 ¾ inches (12 cm) long and weigh a whole 2 ounces (57 grams).*

Pregnancy Week 15: What is happening with your baby?

Your baby’s skin is very thin, and his/her blood vessels can actually be seen through the skin. Your baby’s ears are continuing to develop externally and continue to look more like normal ears. Your baby’s eyes are continuing to move towards the nose from the sides of his/her head. The baby’s bones are beginning to ossify, which means that if an x-ray was taken the skeleton would be visible. Babies at this age have also been caught sucking their thumbs on ultrasound pictures.*

Pregnancy Week 15: What should you plan for this week?

Your healthcare provider will begin measuring your fundus, or fundal height, at your prenatal appointments. This is the distance between the top of your pubic bone and the top of your uterus. Larger clinics where you are not ensured to see the same provider on a continual basis may chart this to measure growth. It can also give insight into the position of the baby. An elevated fundal height can indicate breech presentation, while a smaller fundal height can indicate a sideways position. An ultrasound or pelvic examination can confirm these.

Pregnancy Week 15: Tips for making your pregnancy better

Many women have questions about sleeping positions during pregnancy. It is best to begin sleeping on your side now. This is the most comfortable and healthy sleeping position. Sleeping on your back causes your uterus to place pressure on the aorta and inferior vena cava, which supplies blood to your lower body and the baby. Later in pregnancy, can also make it more difficult to breathe. Sleeping on your stomach also places extra pressure on your uterus and should be avoided.

The easiest way to begin sleeping on your side is to use several extra pillows or a pregnancy pillow. A pregnancy pillow supports your entire body and can range from $40 to $100 or more. Many women find placing pillows behind their backs and between their knees just as comfortable and less expensive.

Pregnancy Week 15: Tips for mom’s partner

Does your partner need help getting to sleep at night and staying that way? Help her adjust her pillows so that she can get comfortable. Offer to give her a foot rub or back massage right before bed so that she is very relaxed and can fall asleep more easily. If you get up in the night or before her in the morning, be sensitive to her sleeping, and remember that it can take her a long time to fall back asleep if she is awoken.
