"i&#039;ve had 3 x mirena&#039;s now. love them. first 2 were great, no pain to get done, bled on/off for a couple of months then no bleeding for 5 years, no mood swings, perfect. i had one put in last october and was in excruciating pain that night. doubled up in bed almost vomiting from pain. i have a high pain tolerance. it has settled down but have only had only a couple of days break here and there from bleeding. i never went back to my gyno for my post check up which i should have done. i went to see my sisters gyno last week and told him how i&#039;d been having trouble so he checked and can&#039;t find iud. going in for surgery friday to get it removed and a new one done. wouldn&#039;t be without one now. advice - if not working how it should get it checked."
