Pregnancy is the carrying of one or more offspring, known as a fetus or embryo, inside the womb of a female. In a pregnancy, there can be multiple gestations, as in the case of twins or triplets. Childbirth usually occurs about 38 weeks after conception; in women who have a menstrual cycle length of four weeks, this is approximately 40 weeks from the last normal menstrual period.
Prenatal care is very important. To help make sure that you and your baby will be as healthy as possible, follow some simple guidelines and check in regularly with your doctor.
