Open sore on vagina..is it herpes?

I'm newly single after a 5 year relationship and have only hooked up with 2 guys since we broke up 2 month ago. Two days ago I noticed this white bump on my vagina while in the shower. It's about dime sized. I've kind of tried to pop it and some clear stuff comes out but nothing really. It doesn't go down or look any better - it's really just an open sore at this point. It doesn't really look like any of the pictures of genital herpes I've look at, or any other STDs or STIs but I have no idea what else it would be. Definitely doesn't look like any ingrown hair I've ever had. I'm going to make a doctors appointment but I was just wondering if anyone had any idea what it is? I'm so nervous. I would post a pic but I can't figure out how to do it.

see on google (Molluscum contagiosum of vagina), if you have the same picture or no?

Thanks! It doesn't look like the molluscum contagiosum to me. I dont know. I'm waiting for my doctor to call me back so I can make an appointment. 

Maybe it's an aphthous ulcer? I do also have a couple canker sores right now.

however don't try to squeeze it as the skin around is inflammed and it may be painful and will not yield any discahrge
