Breech baby

Ricci
I found out a couple of days ago (at 37+3) that my daughter was breech. I went yesterday for external cephalic version. The doctors successfully rotated my little munchkin to the proper head down position and are having me wear a binder on my belly to give her less room to turn herself breech again. Yesterday evening, I started getting very sharp, stabbing pains in my cervix. I called the doctor's office and they were no help at all. They just told me that it "might" be her head engaging and if I start having contractions to go to labor and delivery. So I'm wondering if any of the other mothers have any advice as to what this is or how to manage the pain.
