40 weeks, lost my mucus plug after membrane sweep? Labor?

I am about 40 weeks, second baby and am scheduled for an induction tomorrow. On Friday, I had a membrane sweep to get things going and all it did was make me a little crampy then go away. This morning wiping I saw a mucus plug, how soon after mucus plug or a sweep did you see signs of labor? Or have your baby?

An induction is the best choice for my body and baby right now health wise, but I still really wish I could go on my own tonight. :(

Positive stories? Input?
