Baby's Growth and Development at 7 Weeks Pregnant
During the first 6 weeks of pregnancy, your baby’s heartbeat was the big story. At 7 weeks pregnant, the most exciting event is your baby’s developing facial and physical features. Highlights for your 7th week of pregnancy include:
- By the 7th week of pregnancy, she is 1/3 of an inch to half an inch long now — barely the length of your pinky fingernail.
- Your baby’s face becomes more defined when you’re 7 weeks pregnant. Her mouth, nostrils, and ears begin to appear.
- When you’re 7 weeks pregnant, the lenses in your baby’s eyes begin to form and the iris color is visible.
- Her arms, shoulders, hands, legs, and feet begin to take shape by the 7th week of pregnancy, with the early formation of fingers and toes just another week away.
- Around the 7th and 8th week of your pregnancy, your baby’s body elongates and her neck straightens.
- Your baby’s brain becomes more complex during the 7th week of pregnancy. The skull that’s growing to protect it is transparent and rounding.

Your Changing Body at 7 Weeks Pregnant
Your body continues to undergo lots of change to support your growing baby during the 7th and 8th weeks of pregnancy. Here’s what’s going on:
- Your hormone production increases during the 7th week of pregnancy.
- You might continue to experience some of the common symptoms of pregnancy such as breast tenderness, fatigue, or faintness.
- You might feel like you have PMS (Premenstrual Syndrome) with your emotional ups and downs.
- By the 7th week of your pregnancy, a mucous plug now blocks the cervical canal, helping prevent germs from getting into your uterus. The mucous plug will pass late in pregnancy.
