First & Second DC's by CS, worried about going in to labour

[Number3cometome]

DC1 was born by EMCS after a very long and complicated labour.
I was fully dilated and pushing when I had seizures, so was whipped off quickly for a CS under a GA (went in to labour 39+5, born 40 exactly)

They were taking no chances with DC2, she was an ELCS at 38 weeks exactly.

Currently 33+2 with DC3, I have been having very strong Braxton Hicks from early on in this pregnancy and especially strong recently.

I am hoping to book in for my CS at 39+2.

I just have this niggling feeling that he is going to try and turn up before then.

Anyone have any experience of this?

I think it's stupid pregnancy dreams making me worry, for the last few nights I have dreamt of everything from early labour, to heavy bleeding.

I am sure it's just the usual pre-baby nerves, but seeing as my last DC was 8 years ago, I don't remember having worries like this!
