I was not able to choose unless I went into spontaneous labour early. Then, due to the baby's position (which was supposedly bum engaged, but actually turned out wasn't) I was quite likely to need/want a cs anyway. Data seems to suggest outcomes for planned cs are better than emergency.
I delayed the planned c-section three times to give me more time.

No hospital within half an hour of me offers planned vaginal breech delivery. They are not insured for it and refuse to take the risk. I should know, me and the midwife rang them all

I just wanted my baby to choose his own due date. And I didn't mind if I needed a CS as such, I just wanted to give the baby his own time to turn around. I was amazed by how many people said their baby turned at the very last minute and bam, they went into labour. I wanted that too.
