hello, i took three urine pregnancy tests...two last night, and one this morning. ALL three of them came back positive. but when i went to the hospital this afternoon because i was having cramps in my lower abdomen, the urine test the doc gave me came back negative, but positive for a uti. i am three days late for my period. and i want to know whats going on. then to make matters worse, after leaving the hospital, i went and brought another test, and of course, it came back positive.
