I started at 34 weeks and took 3 Blackmores tablets twice a day. It didn't bring on labour, DD2 was born at 40+5 weeks, but my labour was only 1 hour long so I think that maybe it did help me progress faster LOL But on the other hand my labour with DD2 was only 4 hours, so maybe it would have been fast anyway My gut feeling is though that it helped

Good luck!
