I did had unprotected sex with my new girlfriend 9 weeks back, later I came to know she did had casual sex with other people and states she was having it protected, after two weeks from having sex i had a sore throat and I guess because I was smoking heavily for the two days and was on party shouting at high note from my throat, I was not able to talk clearly for a day, I did had no fever, rashes or any other, but I do have fatigue as I keep on worrying and I guess it is about mental stress and two days back I had a blood blister in my mouth and which made me worry and also I have been consuming large amount of alcohol from last few weeks and which also includes smoking, I'm not sure I sweat at night but I just keep on worrying thinking that I'm sweating at night but I don't think I'm drenching in sweat, this is causing me a complete mind stress. I'm just waiting for few more weeks to take my test but are these some kind of symptoms which I need to worry and I forgot to mention two weeks earlier I asked her to take a HIV screening test and it came negative.
