What is pregnancy?

Pregnancy is the state of carrying a developing embryo or fetus within the female body, specifically in the uterus.  Human pregnancy lasts for ten lunar months or approximately 40 weeks from the first day of the last normal menstrual period.

Pregnancy is defined as the interval of time when an egg is fertilized to birth.  This process usually takes approximately 40 weeks to complete. 
Pregnancy is the time between fertilization and birth in which a fertilized egg goes through stages of development inside the mother's body -- first becoming a blastocyst, then an embryo, then a fetus. A normal pregnancy lasts approximately nine months, at which time a baby is ready to be born.
