Hello,
Welcome to the ehealthforum and I am glad to help you out.
Dilatation of the cervix is in cm and effacement in percentage. When you're ready to push your baby out, your cervix will be 10 cm dilated and 100 percent effaced. If you are having bloody show, then it means labor is near and you should consult your gynecologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
