Natural labour inducing methods.

Anyone pump to collect colostrum and try to get things going? I went over 42 weeks last pregnancy and I’m now 36 weeks. I’ve been given the go ahead to pump starting at 37 weeks if I want to stimulate things and hopefully get things going over the next few weeks! As well as inserting primrose oil, loads of walking, and lots of sex. Hopefully I don’t go so far overdue this time! What are your natural methods to get things going?
