Week 15

Fetal Development:
If you have an ultrasound now, you may notice your baby sucking his/her thumb. The bones are getting harder each day. The baby's skin is very thin and transparent; you can see blood vessels through the skin. Lanugo, a very fine hair, covers the body and will continue growing on the baby until around the 26th gestational week of pregnancy.

Maternal Changes:
Your uterus will begin rising past your hipbones any time now. You can feel it about three to four inches below your navel. During your appointments, your care provider will be measuring "fundal height" to make sure your baby is growing consistently and adequately. Fundal height is the distance from the top of the uterus (fundus) to the pubic bone.
