I had my Mirena inserted at the end of June 2016 and my doctor told me I would be bleeding (spotting) for about 4 months after I got it inserted . I had stopped bleeding after about 3 1/2 months of getting it inserted for about two weeks and after that i started bleeding about as heavy as a regular period . It's been two weeks now since I started bleeding again and I still haven't stopped completely bleeding . I'm not sure what to do or what to expect since this is my first time with an IUD. It's been about a little over 4 months since I got it inserted .
