Turning head down

Okay guys I’m 33 weeks my baby boy is still breech we need him to be head down at my next soon to make sure parts of his heart they still haven’t seen are there (can’t see due to shadow from my belly button and he’s at a weird position) I have a sono on the 18th of July I’ll be 36 weeks is there anything I can do to get him to turn? This is my first baby so not sure I don’t think there is I think it’s just when he’s ready but any ideas?
