HELP! I'm 13 years old and today I noticed that I have a small, pea sized spot/lump thing just beside the opening of my vagina. I'm sexually active but obviously a virgin. It isn't itchy or sore, but its a yellow-ish colour and I'm really worried. I've told my mum but she's unsure and has told me to keep an eye on it for a couple of days- but I'm still panicing:-( please help! Any ideas what it could be and how to get rid??? :(
