I had that done during both of my pregnancies. With my first the dr did it on a monday. My husband (now ex) & I had sex Tuesday then my water broke wednesday morning. With my second pregnancy it didn't do anything. So have sex, walk, do light exercises, and just stay active. Hopefully you'll see your baby soon :)
You shouldn't have that much longer. Go walking and try some stretching. It shouldn't be that much longer..
