I had an ECV with baby no1. It was uncomfortable but not painful! And it worked x
I'm 37 weeks and still breech so having an ECV next week, thought it was worth a try, that and some other things to try as well and then at least I'll know I tried everything before committing to a section x
It's definitely worth a try!
It's worth to try if you want to deliver normally. But completely up to you.
