30 weeks still Breech

So this past week had another ultrasound, He is still breech! Hes killing me, ive tried every trick in the book to turn him but hes lil stubborn butt wont move! My drs dont seem concerned given i still have time but im worried and am starting to have major anxiety over it because i know i wont go another 6 weeks. I have history of early babies, and this is my 4th. I just wish someone would listen to me and my concerns!!!!!
