Getting baby to flip

Autumn

Hi! So I’m 32 weeks and baby is still horizontal. I had a doc apt today and the doc is a little concerned since she’s been measuring big. He said she’s got about 4 weeks to flip or else it’ll be time to schedule a c section. I know I’ve seen people talk about some kinda method to encourage baby to flip but I wasn’t paying attention lol. Any advice would be great!
