Is this an std or something else?
I had sex about three weeks ago with this guy and we've had sex before then too. About two days we had sex the last time, I was felt like I had the urgency to go pee and I just thought maybe I have a urine infection. So I gave it time to see if it will go away and it did. But when I had my period about a week ago, I noticed I was having slight trouble putting a tampon in on the second day. My period was also a little shorter than usual. When my period was over and I was taking a shower, I noticed that my vaginal opening and all didn't feel normal. It felt like a bump was covering my vaginal opening. I told my mother and she told me to put a hot towel and see if it'll go away. In the meantime, we made an appointment for the doc but its in two weeks! But today I noticed it isn't really a bump. Its like the walls of my vagina are swollen and it looks whitish pinkish. I was worried that it was an std, but if it was, wouldn't I have the symptoms of an std in and around my mouth? Since I did have oral sex with him? And he did use a condom after all. But when we had sex for the first time, nothing was out of the normal afterwards. So what could it be?
