J.,
Honey, this could be one of two things at this early stage of pregnancy (possible pregnancy:)] Ovulation or implantation. With my first, I was doubled over with pain during implantation. I thought I had serious diarrhea-type cramps so I was sucking down Pepto LOL! Turns out I REALLY feel implanting. It wasn't like that with my 2nd pregnancy, though. I also feel ovulation. It is more localized (left or right side) so I know which ovary is producing the egg that month. Are you doing any predictors for pregnancy? (Basal Body Temp, OPK's, etc.)
I wouldn't jump on the drug train as you could be in the early stages of pregnancy.
