breech vaginal delivery??

im 34+ weeks pregnant and baby is breech at the mo...my last 2 pregnancies the babys were breech, 1 had to be turned at 37 weeks and the other turned himself at 36 weeks. this time my dr has offered me 3 options if the baby hasnt turned by 37 weeks, a vaginal birth, c section or ecv...

just wondering if anyone has had a breech vaginal birth and how it was for them?
