Honestly it isn't really a big deal, I got one around 36 weeks and used it every day. While it helped with contractions for the short time I was on it before going to the hospital I haven't gotten it out since, I obviously will later on in this pregnancy. I only paid like less than $20 for it so nothing really wasted. So if you wanted to sure, but it wasn't a significant help to me.

I used it while pregnant and during labor.

it helps during pre labor and laboring at the hospital (:
