Why is bleeding coming in girls?

Bleeding in girls, often referred to as menstruation or a period, typically begins during puberty as part of the menstrual cycle. It occurs when the lining of the uterus thickens and is shed if a fertilized egg does not implant. This process is regulated by hormones and usually starts between ages 9 and 16. Other forms of bleeding can also occur due to various health issues, so it's important for girls to consult a healthcare provider if they have concerns.
