There it implants and starts to grow. From the ninth week of pregnancy until birth, it is called a fetus. The placenta is formed from some of these rapidly dividing cells. The placenta functions as a life-support system during pregnancy.

Oxygen , nutrients, and hormones from the mother are transferred across the placenta to reach the fetus, and waste products from the fetus are transferred to the mother for removal. During pregnancy, the lining of your uterus thickens and its blood vessels enlarge to provide nourishment to the fetus. As pregnancy progresses, your uterus expands to make room for the growing fetus. By the time your baby is born, your uterus will have expanded to many times its normal size.

A normal pregnancy lasts about 40 weeks from the first day of your last menstrual period LMP. Pregnancy is assumed to start 2 weeks after the first day of the LMP. Therefore, an extra 2 weeks is counted at the beginning of your pregnancy when you are not actually pregnant.

Pregnancy can be divided into weeks and sometimes days. Each trimester lasts about 12—13 weeks or about 3 months :. The day your baby is due is called the estimated due date EDD. Still, the EDD is useful for a number of reasons. It determines your fetus's gestational age throughout pregnancy so that the fetus's growth can be tracked. It also provides a timeline for certain tests that you will have throughout your pregnancy.

But when the date of the LMP is uncertain, an ultrasound exam may be done during the first trimester to estimate the due date. If you have had in vitro fertilization , the EDD is set by the age of the embryo and the date that the embryo is transferred to the uterus.
