Stripping the membranes can help, but isn't a sure-fire method of starting labor. If your body is not ready, nothing will happen. We can't tell you when you'll go into labor, obviously. Just that eventually you will.
I'm sure your doctor would have sent you had he thought it was necessary. If stripping your membranes starts labor, then you
will be going to the hospital, right? And if you don't go into labor, you're obviously not ready to give birth yet. So what would be the point of going to the hospital. Do you see my point?
You're in your last days. Just relax and try to take things as they come.
