What is pregnancy?

Pregnancy is the term used to describe when a woman has a growing fetus inside of her. In most cases, the fetus grows in the uterus.

Human pregnancy lasts about 40 weeks, or just more than 9 months, from the start of the last menstrual period to childbirth

What are the signs of pregnancy?

The primary sign of pregnancy is missing one or more consecutive menstrual periods. However, because many women experience menstrual irregularities that may cause missed periods, women who miss a period should see their health care provider to find out whether they are pregnant or whether there is another health problem.
