Month 3: Weeks 9-12

Doctor visits

Throughout your pregnancy, your doctor will chart your weight, your blood pressure, and the protein and glucose levels in your blood. She will also measure the size of your uterus at each visit. 

Near the end of your first trimester, you may be able to hear your baby’s heartbeat.

Be sure to tell your doctor if you notice any unusual changes or symptoms between appointments. 

Month 3 baby progress illustrationYour baby 

Your baby’s fingers, toes, ears and eyelids are formed during the third month, and his brain is producing about 250,000 new cells every minute. By the end of your first trimester, your baby weighs about one-half ounce and has grown to about 2-and-a-half inches long.
