I tried Clary Sage. A lot. I had it in my foot spa, I used it in a burner, I put it in massage oils, and did all of these things every day from 39 + 3.

DD was born at 40 + 12

But we tried everything. It was kinda fun trying, we had a lot of laughs, tried to keep it positive. I also took RLT from 30 weeks, right through to almost 42, in increasing doses. I had an amazing (gel-induced) birth, so between the two, I'm sure they did some good, even if it wasn't in that inducing power that we wanted.

Good luck
