i love birth balls. exp the closer i got to my due date. & during labor they are amazing!
It's pretty much a yoga ball.
I used one my whole pregnancy with my daughter I loved it. This time I couldn't find one here where I live. :\
Its actually good for u. It helps relive back pain and helps u open up . baby won't drop until it'sready to, so uusing the ball is ok. I've been using for a while now and in 37 weeks . helps with my back pain !
