Why am I sick

Anyone been nauseous on and off for 3ish days (and counting) no puking, horrible cramps, feeling cold but no fever. I did have (tmi) mushy BMs day one but I'm back to normal now.

I just finished my period last week, I ovulate today or tomorrow. So it's not pregnancy yet....

Can the stomach flu do this??? I just wanna puke and it all to go away... But I can't!! I just dry heaved.
