Vagina Rash...

Alright ladies, I'm having problems here. I have a rash on my vagina but not in, and I don't have any strange discharge. Everything coming out is normal. Where I colored red is where the rash is around. It hurts pretty bad, but my question is has anyone else experienced it? What can I put on it to  feel better? What do you think it could be from?? 
**** Im 16, I'm so far guessing it's from a pad or a condom... I may possibly be allergic to latex, but this is this first within a few months. I will make an appointment to go to a planned parenthood with my boyfriend this week (hopefully) just to make sure... Is there anything I need to know for planned parenthood being underaged?
