Worked for me. I had a S&S with DS1 3 days 5 days before due date, things started happening within about 6 hours. With DS2 I had another S&S 2 days before due date and I went into labour 2 days later. SIL had a S&S and didn't work she was induced in the end.

I guess it is all individual but it would be worth a try if you are trying to avoid the C-Section
