Cramping

Kami

Ok ladies as I've said before I just had my iud removed Dec 14th. Had a heavy Af January 2-7. I dont think I'm pregnant but I've been nauseous and constipated for a week now and today I've had some cramping in my upper right abdomen and now I have cramping/tight feeling in my lower stomach and some shooting pain from there to my vaginal area. Any ideas what it could be. It doesn't feel like af cramps which is why I'm asking. Tia
