Thanks for the query.
Stretching the cervix
and separating the membranes to some extent from the uterine wall helps in inducing the labor.
Usually that can be done near the EDD.
If you are having any indication, the labor can be induced early.
If you are having mucous discharge mixed with blood after stripping of membranes that usually indicates starting of labor.
So if the pains or discharge increases consult the doctor.
