Pregnancy Week 13

This week of pregnancy your baby is about 2 1/2 - 3 inches in length and weighs close to 1 ounce. The growth of your baby's head begins to slow down, compared to the rest of his or her body. Your baby's head has been nearly as large as it's body up until now. Your baby's intestines have moved from outside the body to inside the abdomen. More below:

Changes in You:

You may be feeling better at this point. Many women begin to notice less frequent urination, increased energy and less nausea during their second trimester. Although other pregnancy may arise, such as heartburn, back pain and swelling. The risk of miscarriage in the second trimester, although it still exists, is lower than in the first trimester.
