I got the mirena put in 2 years and 8 month's ago. Everythig was fine and normal, till about 4 month's ago. I started to bleed again every month for a few days. Sometimes it's dark red with a few clots, other times it's just light pinkish red and then thats it. And i get the dang cramps! Im so confused on why im this is happening again after all this time when my Doctor said I wouldn't get a period anymore. I havent seen or felt the iud come out. Also I haven't been ever able to feel the strings. No matter how much i've tried I just can't feel them. Is this normal or should i go in and get it checked out?
