I suggest have plenty of sex or hot showers or walking lots more, i found that them things to help but everyone is different

Apart from intercourse..yes it is supposed to work, you may try massaging and stimulating your nipples as well as the areola. All the best of health to you and bub.

My DIL went gutter walking 1 foot up the gutter & 1 foot down & hours later her water broke & labour started.

Hi there one time after I had the dr examine me at 38 weeks he said go have sex and I did hesitantly mind you I felt like a whale but it worked 7 hours later we had Oliver also another pregnancy we did have some castor oil once it worked and another time it didn’t warning it tastes disgusting ! Good luck xo
