Okay snowbird, I phoned them this morning.
Apparently, homeopathy doesn't force anything so if your body isn't ready then there's a chance it won't do anything. However, he thinks it's probably worth a try, even if it just tones the uterus up to help along.
He's suggested (with me going in for my induction Monday):
Friday night 11pm: Caulophyllum 200 11.30pm: Gelsemium 200
Sunday night 11pm: Caulophyllum 200 11.30pm: Gelsemium 200
Also suggested raspberry leaf tea, but not to go overboard - just 1 cup a day.
Let's keep our fingers crossed that all this helps
