csection or natural

I had my daughter via csection almost 8 months ago. I'm 6 weeks pregnant and I've been reading into what options i have to have this baby - ive red that a majority of women who have their first babies by csection are more likely to have a uterine rupture if giving birth natural in under a year or so.

id much rather have another csection due to this and just because its what i know (as bad as that sounds) i have to take medication daily in pregnancy and cant have an epidural because of this - i want all my pain options open if i have to have this baby naturally.

what are the odds on me having another csection? (i live in the uk)
