sharp shooting pain

Might be TMI for some ladies but oh well, can anyone tell me why I might be getting this sharp shooting pain up my vag. It's so painful. 
I was 1cm dilated last Sunday so does it mean I could be dilating more? 
FTM here. So yea I'm kind of freaking out. I don't see my OB until Thursday. 
Btw, I'm 34+2 today.
