PLS HELP

So I just got off my period and noticed these bumps on my vagina lips, I haven't had sex in 4 years and haven't had oral either. They don't hurt, it doesn't hurt to wipe or anything. There's no discomfort. But I'm scared it might be like herpes or something. They're like little clear bubbles but it doesn't hurt to pee or anything. But let me repeat I haven't had oral or regular sex! Could it still be an STD?
