I've heard fab things about clary sage oil, my friend used it always and she has 6 children! Bath time is best and around due date xx
i used about 5 drops in a carrier oil, still went 2 days over, good luck
I used it in the bath and rubbed it on my tummy day before and day i went into labour. I was 10 days overdue though so who knows if it worked! I did however have extremely strong contractions!
