What does a period have to do with pregnancy?

Answer 1

A period is the term used for the layers of skin to shed from the uterus. The uterus is where the egg will be implanted and cells divide to form a fetus. Every month (in most cases) a woman releases an egg from her ovaries and it travels down the fallopian tubes to the uterus. If the egg is not fertilized by sperm from a male, it will be shed along with the lining of the uterus. If the egg is fertilized, then it will implant itself into the lining of the uterus to develop into a fetus, thus causing the stop of a period during pregnancy.
