Membrane sweep question

So, I go for my 38 week check this coming Thursday, and my Dr said we could start stripping my membranes if I'd like. Currently, I'm almost 3 cm and 80% effaced. I'm just curious how fast it put anyone in labor after having it done? My appointment is in the morning and I'm going to work right after, but I work 1.5 hours from my Dr.
