ECV/ c section at 39 weeks

So my baby has been breech for as long as I can remember and I’ve done every spinning babies technique exercise they have, have don’t chiro, stretching, everything and he still has not flipped. I’m currently 38 weeks. My next dr appt is on weds at 38w3days and my doctor wants me to decide if I want to try and ECV (on Friday- 38w6days) in preparation that if it doesn’t work to go in for a c section- since I would have an epidural from the ECV I could go into either labor and have him naturally or go into a section. I’ve had two other babies both natural so I really don’t want a c section but I’m wondering your opinions on if you would personally try the ECV to see if he’ll flip (but I’ve heard more negative and unsuccessful stories from this then successful), just schedule a c section, or wait another week since I’m still not technically 40 weeks and see if he’ll flip (however they are thinking it’s not likely he’s going to flip) help! I don’t know what to do!
