Stretching Cervix

Melanie • Mommy to a 3 year old Prince. Expecting Prince #2 April 5, 2015
So I am 39w2d. I have an appt with OB in 2 days and he told me that if I don't go into labor before then that he would stretch my cervix to get labor going (only if I wanted to)
Has anyone had this done and did it work?
