I have had the mirena IUD for about a year and a half I haven't had a period for some time now (which is why I decided on that form of BC) I already have a 2 1/2 year old sone. Lately however I have been having some of the same symptoms as when I was pregnant before.. Tender breast, terrible taste, very very sleepy, nausea, head aches. I haven't taken a test yet because I didn't think I could actually get pregnant. I was just wondering if anybody else has gotten pregnant while using mirena and if so what were your symptoms.. I would appreciate any help.. Thanks
