I tried some as I was approaching and then surpassing 40 weeks. Can't really say as they had any noticeable effect for me. I just did a search on Google and I think YouTube had some demos.
Let's see if I can remember and explain the ones I read about: There's one on the outside of your ankle, kind of in the tender part 1/2 way between your ankle bone and the Achilles tendon. There's one on the inside of your ankle, about 3 fingertips up from the top of the ankle bone. There's one at the very outside tip of your pinky toe. There's another in the fleshy part of your hand where the thumb and index bones meet. Another is 1/2 way between the shoulder and C-1. And lastly the sacral bone at the base of your back - it's kind of the flat bone that extends a couple of inches to the sides of your spine, just above the tail bone.
I concentrated on the feet and hand. Good luck - here's hoping!
