When to start?

So ladies I know it’s best the longer princess cooks the better but she is measuring 2 weeks ahead already and I’m getting miserable I can barely walk and in so much leg and back pain ALL THE TIME and can barely sleep. I’m kinda getting over it 😩 but I’m currently a few days away from 32 weeks when is best to start walking and bouncing to try to get things going hoping she’ll wait til atleast 37-38 weeks if the walking and bouncing work??
