I have a Mirena pregnancy scare. I've been using it for 3 years and I've never got my period except this month that I had a very short bleeding, lasted like 3 days but wasn't much, also brown-ish. I also have rare symptoms such as headaches, sore breast and pain, nausea. I've seen people on the internet that has had Mirena pregnancies. Is there anyone here that are/have been pregnant with Mirena or know someone who has? What were the symptoms? How did you find out you were pregnant? Could I possibly be pregnant?!
