Something happened. Anal pain, lower belly pain, big belly pain, what's going on?

Menstruation is a period during which anal pain, abdominal pain and abdominal pain occur, mainly due to uterine contractions.

During the menstrual cycle, the endometrium thickens gradually in preparation for conception. If pregnancy does not occur, the endometrium will peel off and expel menstrual blood. In order to expel the endometrium, the uterus needs to contract constantly, causing pain and discomfort in the lower abdomen, especially in the early stages of menstruation.

When a woman has abdominal pain, she can use a hot water bag or a warm towel to apply to the abdomen to relieve pain and discomfort.
