Random heavy bleeding

Corrin

Hey ladies. So I haven't had a period really since I got my mirena IUD about six months ago. Then a few days ago I started getting bad cramps and last night heavier bleeding. Which is weird for me because the IUD has always made that go away. Do any of you ladies have any experience with this? I'm just curious to see if anyone has been through this before I call the gynecologist. Any input is greatly appreciated.
