I've had my Mirena for 4 months now. I bled heavily for a month after insertion but haven't had a period since. My partner avoided ejaculating inside of me during sex until a few weeks ago. He has done this twice in the past 2 weeks, and each time, a few days later I have light spotting/bloody discharge. WHAT IS GOING ON?? Should I get the Mirena removed?? Also, my strings move A LOT. Not so much that they come out, but enough that I have to reposition them at least a few times a week so we can have sex comfortably.
