I had my membranes swept with my last pregnancy and I instantly started having contractions. The next day my water broke Good luck!!
I had 1 done yesterday and trust me it was uncomfortable and painful. Not trying to scare you but just sharing my experience. I have been losing my mucus plus today which is so gross lol. I also had lots of pain down there which is now easing up. Probably I was a bit sore since she did it. Hope all goes well. Good luck.
