Yes, definitely get one! If you decide it's not for you, it's a small expense. But I found mine was great. I had an all natural home birth with my first, using just a TENS machine and practicing natal hypnotherapy (which I also really recommend) and I was really comfortable. Labour wasn't really painful for me. Intense and tiring (I squatted and pushed for 4 hours, I didn't know my legs could actually be that tired!), but it wasn't really that painful, maybe just uncomfortable. I had the TENS on from the start of strong period type cramps until I started to push (I should have left it on, but actually I didn't I wanted to get in the pool, but I didn't like that, so I got out and didn't put the TENS back on after that). The key to it working though is that you have to put it on when you're still comfortable. The electrical current stimulates the nerves to make your brain produce natural endorphins which block pain sensations, but it takes your body about 2 hours to do this. So don't wait until you actually feel discomfort to put it on. I think if you're getting anything like a faint contraction, slap it on and use it just in case. I put mine on just as I started to have period like cramps, but not actual contractions.
