how long did everyone bleed after Mirena insertion? I wasn't bleeding at all before I got it and hadnt yet had a period because I am breastfeeding...I had my baby 2 months ago today. I have been bleeding for 2 weeks and a few days, since the day I got it placed. Is this normal? I never had this happen when I had Mirena in the past.
