If menstruation has been delayed without coming and there is tummy pain, you usually need to consider the following conditions: 1. You need to consider cervical adhesions or cervical adhesions, which are usually related to endometrial damage and are commonly seen after the operation to clear the uterus and after abortion. Patients with cervical adhesions or cervical adhesions are prone to missed periods, and they feel their stomachs swell significantly during their periods and are cyclical. The best treatment for this condition is adhesiolysis under hysteroscopy.2. Pregnancy needs to be considered, which can easily be caused by women who do not have good contraceptive measures. Therefore, when stomach pain occurs after menopause, it is still necessary to do an examination to determine if you are pregnant, and in addition to exclude ectopic pregnancy. 3. There are other gynecological diseases that can cause delayed menstruation and stomach pain, such as ovarian cysts and uterine fibroids.
