I’m 34 weeks but going to start the ball at 37 JUST INCASE 😅
I got mines when I was about 12 weeks. I used it on&off. I'm 32 weeks now & use it daily!
I got mine around 16-19 week to ease back pain and never stopped using since. I don't exercise on it, just sit down instead of using a chair
I got mine from like 25 weeks to help with hip and back pain
