Definitions of terms related to the anatomy of a fetus in utero.
A healthy first trimester is crucial to the normal development of your baby. You may not be showing much on the outside, but inside, all the major body organs and systems of the fetus are forming.
During this trimester, the weight of your growing baby will multiply more than 7 times — and you will start showing more.
The third trimester marks the home stretch for your pregnancy. You may feel more uncomfortable now as you continue to gain weight. You also may have false labor contractions (called Braxton-Hicks contractions).
Multiple pregnancy is a pregnancy with 2 or more fetuses. In the United States, the multiple birth rate is rising.
Certain tests and screenings may be scheduled during your pregnancy. Your health care provider will advise you on which tests you'll need.
