Hello dear Understand your concern Pain occur due to uterine contraction mainly, but it is not persistent. Following are the other causes: retain product, infection, ectopic pregnancy, ovarian pain. I advice you to consult the gynecologist and get the done investigations like USG scan, swab test, ovarian follicle study to exclude the above causes. Retain product and ectopic pregnancy needs surgery to cure and infection needs antibiotic treatment. Meanwhile take proper rest, tablet ibuprufen, Tablet panmax-D, healthy diet with iron and vitamin supplements. Hope this may help you Best regards Dr. Sagar
