I'm really sorry, but I can't help you either way.
I had 3 vb's & after reading some stories on here they were all great.
I also had no stitches, so I can't empathise with you there either.
I think maybe you could book the c/s after your due date. You might get the chance to go naturally, & then you might have the choice.You can see how you go with the labour & if it gets too much go up for the c/s.
I don't know what I'd do. Well to be honest, I'd probably go for the c/s.
I hope you work it out soon.
Goodluck. Sorry I wasn't much help.
