Hello dear I understand your concern I think you have side effects of the implant as it cause prolonged and excessive bleeeding. Other causes could be a pelvic inflammatory disease, vaginal infection, endometriosis, hormonal imbalance. I would suggest to consult the gynecologist and undergo reproductive hormone analysis, vaginal examination, USG scan and endometrial biopsy. Bleeding can be reduced by the progesterone pill and tranexamic acid. Provera progesterone can be used. If not responds then remove the implant and use another method of contraception. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
