I have had sex with a girl I didnt know 4days ago and its starting to hurt to piss and well my heartbeat is crazy but I have also been using meth starting 4days ago and kept smoking it till today. I now stopped on the fourth night got some sleep and well when I pee it hurts when it comes out the tip. Im wondering if its Hiv and I can tell after the couple days or if its urinary tract infection. I need help
