Welcome to 'Ask a Doctor'. Please type your question here... so there is the chance that I think I could be pregnant. The timeline has been I had sex like August 20th, then took a test in the middle of September at home and at the doctors. They were both negative then I went to the ER and had another negative urine test, then just last Friday I bad another negative urine test, the doctor I saw gave me antibiotics for a uti but I feel like a uti doesn't explain like half of my symptoms and it didn't make any difference for me and I took all of the medicine and finished it today. My symptoms are back pain, stomach pain, upset stomach, nausea, frequent urge to pee, more tired, have had a couple headaches and been dizzy and lightheaded once or twice. Nowhere I have been has took any blood pregnancy test though, what do you think?
