problems

So I have bit of a problem and I don't know what it is. The other day I notice a little red bump on the inside of my vagina lips. It does hurt. I did have sex for the first time two ago. It has been two days since the bumps have been there and they haven't gotten any betuter. I look at them earlier and notice that they are turning white. I was looking it up on the internet and everything that I found said it was herpes. I am hoping that it is not. Is there any way that it is herpes and my a just a pimple. Can someone please help me I'm freaking out?
