Membrane stripping

Lilia
Okay so today, I had a check up. I'm 39 weeks 4 days. Doc asked me if I wanted to be induced last week at 38 weeks. I said no I would like my labor/delivery to be as natural as possible. I'm dilated at a 3 almost 4 cm. My doc stripped my membranes today at around 2:30 p.m., I had already been contracting before today. But contractions had been 15-20 min apart. Since then my contractions have been about 7 min apart. My question to those who have had their membranes stripped, how long after did it take for your labor to start and have your baby?
