abnormal uterine bleeding
"I had been having really heavy and painful periods for about 3 years when i decided to get the mirena. A few weeks later i had the most painful period ever. my gyno said to try it for at least 6 months to let it settle in and I'm so glad i did! My periods since that one haven't been a quarter as painful as they used to be and i hardly bleed!  i used to have a 7 day period with such heavy bleeding the first three days I'd have to change a maxi tampon every 2 hours.  Now i don't even bleed enough to use a mini tampon! just a panty liner. I also haven't noticed any changes emotionally or physically ( other than the lack of pain). I'd recommend ppl wait a few months before getting it removed, it's worth it in the end! I love it!"
