Fetal Development Month by Month

From conception to delivery, each month will reveal new developments and growth for your baby. Although each baby progresses at its own pace, this fetal development guide will give you an idea of what's happening inside your womb each month.

Month 1

This month you will miss your period, your breasts might be swollen or tender, and hormones are surging through your body, preparing you for the coming months.

Month 2

You may discover the unglamorous side of pregnancy this month: nausea, morning sickness, and fatigue will begin to take hold.

Month 3

Fetal developments in the third month will take a turn. This month your baby's organs will continue to grow and the sex organs will become clear!

Month 4

This month your baby looks increasingly human but still cannot survive outside the womb. Many women say their second trimester is the most enjoyable. Learn more.

Month 5
