I had unprotected sex once with a guy on April 10th of this year. Completely ridiculous, I know! I have been crying out of guilt since the day it happened! This last week and a half, I have been having a burning sensation when I pee. I have been feeling sensitivity/irritation in my clitoral area. I have also been having sudden slight pains in my pelvic area and lower back, but this may due to my period since it should be coming in a couple of days and I always get PMS symptoms about a week before. I have had no sort of strange vaginal discharge, or any ulcers/sores/blisters as far as I can see. I do have two very tiny pimples on my left butt cheek, one tiny pimple on my chest, and one very tiny one on my right thigh. Could this be a UTI, a yeast infection, or is there a high chance of it being genital herpes? I think I am losing my mind! I was first terrified of having acquired HIV for absolutely no reason. I had a little rash on my back so I started freaking out. I had an HIV test done at 9 weeks and it came out negative. Now, when I finally get over the anxiety of that, I am now getting anxiety over having contracted Herpes. Someone please help! I need some peace of mind! Thank you!
