Vaginal itching but no pain?

I am a virgin, I haven’t done anything down there, but a day or two ago it just kinda started with slight uncomfortable itching right below actual entrance. And it’s just increased. It definitely isn’t constant but when it itches it’s uncomfortable!! I’m super confused why this is happening. It started the day after my period ended. I use a menstrual cup!:) help! Yeast infection without pain?
