If there is a history of menopause and stomach pain, the first thing to rule out is the possibility of pregnancy. It is recommended that an HCG test with early pregnancy test strips or a blood HCG test with blood drawn will be more sensitive. If there is a positive result by blood HCG or urine HCG test, it indicates pregnancy. Depending on your wishes, you can have a pre-abortion test if you want to terminate the pregnancy, or go to the obstetrics department for further tests if you want to continue the pregnancy. If you are not pregnant, the vast majority of cases are caused by endocrine disorders, in which case you are probably going to have your period. The stomach pain before and after or during the menstruation is clinically considered to be a clinical manifestation of dysmenorrhea. You can take progesterone orally to induce menstruation, once a day, two capsules at a time, for 3 days, and usually menstruation will come 3-7 days after stopping the medicine. If you still have lower abdominal pain after menstruation, it is recommended to go to the hospital for examination to exclude the possibility of other diseases.
