Punched in the vagina?

Hi ladies earlier today I was sitting at the dining room table and all of a sudden my vagina felt like it had just gotten punched really hard and started throbbing. It only lasted for maybe 30 seconds and the only ever time I felt this was maybe a few months ago. I looked it up on the internet but came up with invalid answers as I’m a virgin. Can someone tell me what it might be and if I need to see a doctor? Thank you!
