Women should be alerted to the presence of pelvic inflammatory disease if they experience abdominal pain and anal cramping after intercourse. If it is caused by pelvic inflammatory disease, an ultrasound at the hospital at this time can reveal a large amount of fluid in the pelvis. Patients with endometriosis may also experience pain in the abdomen and anal pain, and this is the time to go to the hospital for symptomatic treatment. Patients with ectopic pregnancy cannot be excluded if they do not have menstruation at the time when they should have menstruation and have pain in the abdomen after intercourse. If your period is normal and you have pain in your abdomen after intercourse, most of you will consider the possibility of pelvic inflammatory disease, which can be clearly diagnosed through gynecological ultrasound and internal gynecological examination.
