I'm not sure where to post this. I had my mirena out towards the end of January. I had a few days of bleeding and then I stopped and then I started again for a day or two. I still have not had a period and I've been feeling super nauseous. My husband and I have had sex but we have been using condoms at because I'm not on birth control. there was one time that the condom was on but when we got finished it had come off . Should I be concerned that I'm nauseated or am I just being paranoid??
