Can an std test show negative after 1 dose 500mg of amoxicillin?

I had oral, vaginal and some anal play sex 3 weeks ago. A week and a half ago my urethra started itching, then a few days later it started burning when I was urinating. I went to a lab and had an std test done for chlamydia and gonorrhea only. It came back negative. It was a urine test. Then I called a doctor and he prescribed me 500mg Amoxicillin 3 times a day for 10 days. I went in again to get tested for all stds a day later but I had already taken 1 pill of amoxicillin. The urine test came back negative again and the blood test is not done testing yet. I am still having the same symptoms with little improvement 3 days on amoxicillin.

I am worried that the first test may have been bad because I urinated quite a bit in the cup and when I went in the 2nd time, the nurse told me that the urine needed to be concentrated, only a very small amount in the cup, which I did the 2nd time. Any advice would help here. I am very worried and I do not have a regular doctor established since I just moved recently.

One final note, the girl I slept with has no symptoms and says she was tested with all clear results fairly recently.

With an std there would be a white puss discharge which is the true sign of an infection. Try milking your penis in the morning before urinating so see if some come out. On a side note urethrea itching is a symptom of Chlamydia.

Maybe an injury from the act itself for your causing it from constant touching check for things

There is no way. This came on very gradual. Its definatley an infection of some kind. I just don't know what.

Hi symptoms of gono and such would be a white puss discharge and burning while urinating about 5 days later. both tests would be accurate
