I had a planned c - section with my first (was a lovely experience).
Yet, wanted to try for the natural birth 2nd time round. I was overweight (obese, of BMI 40) and only 2 years passed from my previous c-section.
even taking all that into account I was approved to have a natural Home birth.
so, they can not force you to have another c-section, if you don't want to.
My second birth ended from home birth to the emergency c-section, after 36 hours of labour! We both almost died... recovery was horrible and nothing like my first, elective c-section...
I do not want to scare you, but, if you have 40 % chance of a natural delivery... Maybe go for an elective c-section? I just want to tell, that there is a WORLD of difference between an emergency c-section and a planned one.
This time around I am still undecided about my choice of delivery. First I wanted to try to go for vba2c, but now am reconsidering... I definitely would rather have an elective c-section then another 36 hour labour and end up with an emergency one!
Good luck and hope that whatever choice you make, will get you a supportive medical care
