premise: I was in the hospital saturday morning becuase i was cramping and having alot of pain in my pelvic area . They tested my urine and said there was no blood in it but they were going to give me an antibiotic becuase he thought something was going on . I was in the doctors on tuesday of my weekly check up and they said everything was fine how can something change so fast ? What may have caused your visit to the hospital ?
hypothesis: I was experiencing intense discomfort because of the antibiotic .
