19 weeks pregnant
Second trimester about 4 months
At 19 weeks pregnant, your baby is about the size of an artichoke.
Baby this week
About 150mm. The fetus is developing a white waxy coating called vernix caseosa that protects the skin. Hair on the scalp is beginning to sprout.
Did you know? Vernix caseosa — the white, cheesy coating on the baby's skin — acts like a moisturizer and protects delicate skin from amniotic fluid. Some babies are born with it still on.
