Your Pregnancy: Week 15

What’s your baby up to these days? He just might be sucking his thumb. In fact, you may be able to see this in an ultrasound at this point in your pregnancy.

Your baby

• If you could hold your baby in one hand and a baseball in the other this week, you’d see that your baby is noticeably larger but much lighter than the baseball. From the crown of his head to the bottom of his buttocks, he’s about 9 to 11 cm (3.6 to 4.5 in) long, and he weighs close to 50 g (1.75 oz).
• Your baby is covered with fine hair called lanugo, which will disappear before (or soon after) he’s born. The hair on his head is beginning to grow and his eyebrows are filling in.
• His eyes are continuing to move toward the front of his face and his outer ears are still developing.
• At this stage of his development, your baby’s blood vessels are visible beneath his thin, transparent skin and his bones are quickly hardening. In fact, if an X-ray was taken of his body now, you would be able to see his bones.

Your bump

You can clearly feel the top of your uterus now, about 7.5 to 10 cm below your bellybutton. But it will probably be another three to four weeks before you feel your baby move.

Eating for two

With early pregnancy queasiness subsiding, you likely have more of an appetite these days. That’s a good thing: at this stage of pregnancy, you need about 300 extra calories a day to sustain your baby’s rapid growth and maintain your health. So if you feel hungry, eat!

Quality is important though. If your diet hasn’t been the greatest, pregnancy is the perfect time to pay more attention to what you eat. Start with Canada’s Food Guide, and add an extra nutritional punch with pregnancy power foods.

Why are my gums so sensitive? Sometimes they even bleed when I brush my teeth.

The extra sensitivity in your gums is caused by the hormonal changes in your body during pregnancy. Those changes also make you more prone to gingivitis (gum disease), so regular flossing and dental care is extra important. If your gums become really irritated, ask your dentist to recommend alternative ways of brushing and caring for your teeth.

Looking ahead

Will you be pregnant during flu season? Plan to get a flu shot — it will not only protect you, it will also reduce your baby’s chances of getting the flu after he or she is born.
