Your baby at 15 weeks

Your baby is the size of a small grapefruit during 15th week of pregnancy. weighing anywhere from 48 to 70 g (1.7 to 2.5 oz) and measuring 10.4 to 11.5 cm (4.1 to 4.5 inches) from crown to rump.

Hair today

Your baby’s hair pattern is established during 15th week pregnancy, but this is no guarantee that he or she will be born with a full head of hair. Ultra-fine, soft hair, called lanugo, is also appearing over your little one's entire body. This downy hair protects the delicate skin from the amniotic fluid and usually disappears just before or after birth.


Underneath that lanugo is a fine layer of skin through which you can see blood vessels already transporting blood. Mouth development continues and baby’s face is capable of moving more and more.

Swollen hands, feet and ankles

This swelling, or oedema, is caused by the increased blood circulating through your body and the pressure of your growing uterus on the pelvic veins. Mild exercise is a great way to keep swelling at bay, so try walking, swimming or taking a yoga class. Read different forms of easy and comfortable exercises during pregnancy here.
