how long has the doe been pushing? if it's more than 1/2 hour she needs help. if the cervix is partly dilated, you can stimulate it by gently pressing on the rim of the hole, going around the circle, and it might help it to dilate further. I had to do this multiple times with my last doe and eventually was successful. hopefully more experienced people will give you advice. keep us informed.
