My OB works out the scale with 5/5ths as the starting point and fully engaged is 1/5th.

Some OB's are known to be the opposite, but I thought I'd share that with you because you may not be as far engaged as you think Ask your OB how their scale works.

Pains in the cervix are quite common too. I had lots and liken them to being prodded with a skewer up the hoohaa! Most uncomfortable.
