Ive gone two years without a period with my IUD, nothing at all. Ive been cramping up for over a month straight everyday and yesterday i started bleeding like a regular period again. I went to the hospital a few weeks ago and i was negative for pregnancy and they could see my strings in place. Im waiting a week or two to see the results of my recent ultrasound. Im nervous its cysts or fibroids or ectopic pregnancy or my iud has lodged itself somewhere. When i got the ultrasound i wasnt bleeding. Im scared that there is something really wrong and i have to wait a while to find anything out, should i go back to the hospital or just wait until my doctor can see me in a week or two? My mom had ovarian cysts and they burst and she had to take an ambulance. I have no idea why this is happening. Please help!
