Had Unprotected Sex. White Bumps And Itching In Vagina. What Could This Be?

Question: Hi , I am 19 years and honestly this last month I've been a lot more promiscuous then I would like to admit . Anyway I had a one night stand a few weeks ago , and didn't use protection, now im having serious irritation in my vagina , and I'm freaking out! thinking back on the night the guy I slept with didn't show me his penis all night , like it was always under the covers or dark which is unusual. At first I thought that I had a yeast infection. The lips of my vagina is extremely irritating , and itchy! the inside of my vagina lips are also extremely red , and I even wake up in the middle of the night with need to itch my vagina! But I've had a yeast infection before and it was constant discomfort, and this randomly doesn't hurt very much then an hour later the itching and burning comes back , also I looked in the mirror at my vagina and there is a whole bunch of little white bumps on the inside of my vagina lips .My first thought was oh my god I have herpes ,but then I started to Google herpes and the pictures were all of blisters, which I don't have on my vagina there's just white bumps. I'm going too a STD testing clinic in the morning but I'm so scared I cant even sleep and would really like someone's opinion on what they think it might be ... Also im wondering if the white bumps can occur during a yeast infection ? and also the inside of my vagina is extremely red , and irritated, it burns a little when I pee, would you think its a yeast infection or could this be some kind of std ?
