Sorry my experience is not what you want to hear either. I had a sweep every week during the last 4 weeks and each time the mucus plug came away. I also had contractions 5 mins apart for half the night after each sweep as well. The good thing was that each week I dilated 1/2 cm more (most likely due to the sweep and contractions).

I hope this isnt the case with you and it kickstarts real labour.
Sending lots of labour vibes your way.
