Never Started Menstrual Periods

Painful monthly cramps without any bleeding may be a sign that your uterus is trying to squeeze out menstrual blood, but the blood cannot pass from your body. This is the case when something is blocking your uterus, cervix or vagina due to abnormal development in one or more of these areas.

Proceed with arranging a doctor's appointment or talk with a parent or guardian to help you. You want to find out if you have some blockage of menstrual blood flow.
