Hello, I have been on amoxicillin 875mg 2x per day for two and a half days. I am not suppose to start my period for another week. I am bleeding enough to be like a period, and I feel faintish but I'm not cramping severely. I haven't had a reaction to antibiotics like this ever. My tummy also seems poofy or swollen. I read online about affecting estrogen but shouldn't that just be spotting? Also, about two months ago I had a PET scan and cat scan, but I've already had normal periods since then, so it shouldn't be that. They were checking me for lymphoma but I'm fine. I also suspected pregnancy several weeks ago but I had my period. Should I stop taking the antibiotic or not? I'm not sure what to do since it's the weekend..
