I've been getting this awful burning pain on the inside of my vagina the last couple of days. Just a quick shooting pain. It isn't all day, usually mid day it will happen and it's very short. Probably about 10-15 seconds long and it will happen 4-6 times before stopping. I read online that it could be my daughter is head down and pushing on the cervix or that I'm beginning to dilate. About all I could find, but does any one else have a different explanation? I'm 33 weeks
