Vaginal health

alright, so I’ve had a vaginal itch for a few days now. Since about Tuesday maybe? Don’t really remember. But, i don’t have any discharge, pain with peeing, i do have some pain during sex but it’s not unbearable, i have the urge to pee a lot but again no discharge, and this might be TMI but the itch is on the inside. I’m on birth control and vitamins but that’s all i take. Any idea what this could be?
