Mirena Iud

Hailee

I got the mirena iud placed in july. My periods have been slightly irregular, which my doctor said is normal while my body regulates to it. But my only concern is I bleed after sex everytime. It’s usually the following day I bleed, usually just slight bleeding light pinkish. I’ve never bled from sex before so i’m sure it has to do with the iud since it’s been happening for almost 3 months now. Is this normal?
