krystals I think I know what you mean....in the few days leading up to DD's birth I described it as almost like an electric shock right down low in my pelvis, wasn't accompanied by an other sensation, just a real spark right up and inside me. When I explained it and tried to point out where, the MW and my doula both said it seemed as though I was describing feelings right in my cervix, and was most likely pressure from bub/cervix getting ready. It was a really bizarre feeling!

Whatever it may be, good luck!
