I have had the mirena now for about three years. The last few months I have experienced bouts of severe pain in my stomach almost every day, breast tenderness, slight lactation, and this awful nauseous feeling (even though I have never actually thrown up). I went without a period for three months and then suddenly had one at the beginning of February. I felt better for a couple of days after that, but then everything came back. Can anyone help me? I'm really worried, but I don't have insurance and when I went to a free clinic all they did was give me a regular stick pregnancy test and tell me I wasn't pregnant.
