STD exam failure?
I am 19 and sexually active. I had unprotected sex witha girl at college about 3 months ago and nine days later had an STD screening all results were negative. I am wondering if there is any way the test could have failed? It was a urination test. I have had epiditymitis before and am now having similar side effects and am wondering if it is that or a faulty STD exam? Is there anything that wouldn't show up nine days later?
Thanks for your time
