abnormal uterine bleeding
"I've had mirena now for 10 days. I started spoting 2 hrs after the placement but my Dr told me I might bleed for up to 4-6 after placement. I've only had 1 really bad night where I cramped so bad it woke me up n I had to take meds. As time goes on I notice less bleeding and no cramps. I'm happy with the mirena so far."
