Can medical abortion cause PID?

Not likely. If you have chlamydia or gonorrhea undiagnosed recently then it might be a coincidence. endometritis (an infection of the lining of the uterus) is more common. IF you got this diagnosis is the ER, be aware ER's often times use this as a go to diagnosis for pelvic pain. Get a GYN consult regarding this as PID is often times not the correct diagnosis.
