Contact [7]

Answer:

Explanation:Simply put: A period is when a woman's body releases tissue it no longer needs. ... Every month or so, the uterus lining gets thicker to prepare for a fertilized egg if the woman becomes pregnant. If the egg doesn't get fertilized, that lining is released from the body as blood through the vagina.

Period pain is common and a normal part of your menstrual cycle. Most women get it at some point in their lives. It's usually felt as painful muscle cramps in the tummy, which can spread to the back and thighs. The pain sometimes comes in intense spasms, while at other times it may be dull but more constant.
