I have been induced with all of mine, first was at 38 weeks and took 3 lots of gel before they could breakwaters and put drip up. From first gel to bub born was aprox 35 hours but labout was 17.5 hours. Don't let them push you if it taking awhile to dilate, I took over 12 hours to go from 2cm to 6cm and then 5 more from there to pushing.

Second had gel, then had to wait as they had to many non induction labours, then once they broke waters and put drip up was less than 4 hours.

Third no gel, waters broken, drip again less than 4 hours

so it can all be different.
