As the other said, you should definitely have a thorough examination done with sharp sudden period pain like this.
I had very bad period pain when I was younger, it has subsided through age. I was basically inmobile on the first day. I would be at school, as soon as the pain started, I became drowsy, the pain would just make me lie on my desk and passed out, normally it'd last the whole morning. If it started at home, I would have to skip school. But this is nothing compare to my mum, when she was young, she had passed out on the street and sent to the hospital; or her brothers had to bring her to the hospital for shot for a few occassion. I think it's hereditary.
