abnormal uterine bleeding
"Was on mirena almost two years and it was very bad. Bleeding non stop after insertion for a couple months , and now it's been out for almost 6 months and I've been bleeding a lot again. I spotted 3 times in between my periods this month and my doctor said around 6 months after my periods would be back to normal... well they are not at all! I'm going to see when my doctor can see me next week because this is out of control. Worst birth control. Should have tried the depo provera or just birth control pills again"
