Great orgasms at first then terrible pain!!

Vicki
Yesterday I was with my bf and we began to fool around. We made out felt each other up then he began to finger me. It was amazing of course but after the 3rd time he made me orgasm I began having this horrible pain in my vagina. Im not really sure how to describe it. It was like I had something blocking the entry way of my vagina and it was being pushed back further in when my bf was fingering me. It got even worse when I was at the point of orgasming. I'm gonna see my doctor of course but it's going to take maybe two days or more because she's always booked =/ do any of you guys have an idea of why I suddenly had this pain? Have any of you galls had this before?
