Hello madam, Welcome to healthcaremagic. I can certainly understand your concern I have worked through your query in detail The symptoms you are experiencing are definitely due to the side effects of MIRENA , like irregular periods, pelvic pain , head ache and depression. It would take some time for the body to get adjust to this mirena and these symptoms resolve on its own, in the meanwhile you can take some drugs like meftal spas to get relief from your abdominal pain If they persists and bothersome, you can consult your physician and go for another contraceptive like paragard. you can start some antidepressants like escitalopram which make you feel better. Please check with your physician if she shares my view Post your further queries if any. Thank you
