13 Weeks

Week 13

How Big is the Baby at Thirteen Weeks Pregnant?
During pregnancy week 13 your baby is anywhere from 2 and a half to a little over 3 inches long and weighs up to .7 ounces. Though your baby is significantly larger by pregnancy 13 weeks, he is still pretty tiny. Fortunately there is plenty of room to expand in your uterus as you follow your pregnancy week by week!

Your Baby's Growth and Development
By the end of pregnancy week 13 your baby looks like a tiny yet fully formed baby. While your baby's head is still quite large, his body is starting to catch up. Your baby's eyes are starting to move closer together by pregnancy 13 weeks. Up until this point in time they rested closely along the sides of the head. Your baby's intestines are also moving further into their body, and your baby's tiny pancreas starts producing insulin, which will be vital for regulating your baby's sugar levels later in life!
