I have the Paraguard IUD too and it was hella uncomfortable when I had it inserted and I was crampy for about 2 weeks after. The periods will be very strange at first: longer, heavier and crampier but they do start to get better. I've had mine for a little over a year now and so far so good. Aside from my period stopping then starting I'm doing well with it. I wonder if anyone else has noticed this? You are more likely to expel the IUD in the beginning because your uterus isn't used to it yet so it's good you are going to the doctor soon.

I too used this method as a last resort due to migraine headaches from hormonal birth control. I think it has worked out for the best. Considering my state during a bad migraine compared to crampy. I can deal with crampy but I can't lock myself in a dark, silent room for a whole day if you know what I mean.

Let us know how things turn out. Best wishes and try to take it easy and not get too freaked out. It's most likely something simple but you are smart for being careful.
