The pain in the belly after sex may be related to endometritis and pelvic inflammatory disease in women. The pain in the belly will be relieved by proper rest, hot water and distraction. If the pain in the belly is more intense and lasts longer after sex, it is best to go to the hospital for gynecological ultrasound and gynecological checkups. If a woman has an ovarian cyst or a corpus luteum cyst that has twisted or ruptured during sex due to rough movements, she needs to be actively treated with surgery. It is not normal for women to have stomach pain after sex, so they should actively look for the cause for symptomatic treatment. When women are pregnant, they should also pay attention to the occurrence of pre-miscarriage when they have stomach pain after sex.
