I hate it. I got a medium size because it was the smallest they had but I'm 4'11" and its huge on my back. It keeps bunching up and is so uncomfortable. I've tried it tighter. I've tried it looser. I thought it would relieve pressure from my baby being on my bladder all the time making me have to pee with every move I make but nope. It does relieve my stomach muscles from feeling like they're being pulled but it's just so annoying.
