I just finished having sex and im experiencing mild - severe cramping in my extreme lower abdomen. it almost feels like period pain. it' hurts to move?

See doctor: Sudden onset of pain is concerning, especially if it is severe! if you are still having severe pain, you need to go to the emergency room.

My 1st answer-males: Possible: uterine cramping common like mild period cramps common after orgasm. Right-sided pain with fever/nausea/vomiting may be brewing appendicitis. Std with pelvic inflammation causes generalized lower abdominal pain. Ovarian cysts can burst or ovaries can twist and become torqued causing severe one-sided lower abdominal pain. See a doctor asap. Torque and cause one-sided pain.
