I got the mirena put in the first week of January. It’s now almost March and I’m still bleeding. It’s heavier when it’s time for my period (which last around 10 days), and everyday since I had it put in I have at least light bleeding. The cramps are also the worst I’ve ever experienced and occur 2-3 days a week. Is this normal? How long did it take for your cycle to regulate and/or for you to stop bleeding/cramping?
