I was recently seen in the ER for lower abdominal pain, and was diagnosed with an acute urinary tract infection. My abdominal pain wasn't diagnosed, but I was given an antibiotic for the UTI. I took it twice a day for 7 days, and then about 3 days after I stopped taking it I began to vomit uncontrollably all day every day, and I'm still doing it. I was given blood tests at the hospital and would assume they would inform me if I was pregnant.Do u have any idea what else it could be?
