Ive had 4 c/s...and yes 3 of them were elective adn with all 3 I went early.

DS2 - waters broke in therate as I was being place donto the 'slab'
DD1 - I was booked in for the utesday with 2 of my friends...seems she didnt want to share her bfday and went into labour midnight friday....had emergency c/s at 3.30 in the morning.
DS3 - labour began 3am the morning of the booking.....was ment ot be last on the list, ended up being first at 7am.

Let your doctor know your feelings at your next appointment.

FTR - my best c/s was with DD even though it was a hard labour I had no pain ect after my c/s at all
