14 weeks pregnant
Second trimester about 3 months
At 14 weeks pregnant, your baby is about the size of a lemon.
Baby this week
About 85mm. The fetus is developing fine hair called lanugo. The roof of the mouth is forming, and facial muscles allow for squinting and grimacing.
Did you know? Lanugo — the fine, downy hair that covers the fetus — begins developing this week. It helps regulate temperature and will mostly disappear before birth.
