never mind your conditions, i believe womans intuition is always spot on..... personally i wouldn't risk another natural..
i was huge with ds1 (big now with ds2), had a private scan at 34 weeks and ds was basically at term size, raised my concerns with midwife who sent me off for another scan at 37 weeks with consultant appt straight after...
sonographer was relieved to know i had a consultant appt right after her, i really thought they may induce me at 38 weeks (big babies tend to get bigger and stay longer) but consulant said not all inductions work and safer to go straight for elective cs at 39 weeks....
so there went my plans for a natural water birth and all the perinial massage out of the window!!
anyway,the birth, surgeons struggled to get ds out as he was so big (used forcepts in the end) and in the end said that this was the only way out for ds... so relieved i didn't push for an induction!!
i am going for an elective cs again in november....
as long as healthy baby and healthy mum i would push for what you want, i was terrified of pushing out a big baby (every percentile head, length etc on the scan results off the radar) and so glad they didn't make me as it could have been a very dangerous situation....
the cs was very professional and civilised...
i know so many mums who have ended up having emergency cs's even after dilating to 9cm (2 friends!)!! it's so common unfortunately.
good luck x
