I had teh Mirena inserted in February 2009. The last two months I have had BAD back pains, hair loss,hair loss,hot flashes and headaches like crazy!! At first I thought something was wrong with me other than side effects from the Mirena but when I found this website and read the comments..... I ALMOST LOST IT! I will definitely be having this removed! I can't take it!! Not only that I bleed at any given time of the month sometimes light sometimes not!! Now I'm scared they won't be able to find it! The first couple of months I didn't see or remember any side effects but now they are definitely there!!!
