Wish you luck with your sweep! having discharge is completely normal after having one , I had one last Tuesday and I had bloody show for over a week , with on and off contractions but no baby :'(
Spotting is normal for a couple days and cramping and maybe some contractions. Hope it works for you. Good luck!
Once when you get membranes swept you'll spot for a bit and have a cramp in your stomach. So its completely normal
