###Human: My periods are not regular after my abortion. What should I do? ###Assistant: Hello. If there is a history of sexual intercourse after abortion, then I would suggest you do a blood test and serum beta hCG (human chorionic gonadotropin) after 10 days of intercourse. Also, I would advise you to do one pelvic ultrasound and serum beta hCG to rule out any retained product of conception. If everything is fine, then you can take OCP (oral contraceptive pills) for three cycles to regularize your periods. Please do a pelvic ultrasound and serum beta hCG and send me the report.
