How is my baby growing and developing during week 11?

In week 11 of pregnancy, your baby, who is officially considered a fetus by this time, is continuing to grow and develop very quickly. Your baby's head still makes up half its length, but its neck is now forming more fully and the body will soon grow to catch up with the head. Feet and hands are no longer webbed, and your baby may actually be starting to develop tiny fingernails! External genitalia are starting to become more distinct, though you still won't be able to tell whether it's a boy or a girl for a few more weeks.
