I'm 41+1 today and been having irregular contractions all week.
I had an odd experience last night - began to feel sick and have contractions every 30 mins - and felt sort of 'drifty' iykwim, and I thought 'this is it'. But then we started watching a documentary about the second world war and I thought maybe I don't want to bring a baby into such a world (I do realise it's a bit late to be thinking like that now!). And I kind of snapped out of it and the contractions stopped.
I wondered if anyone else had experienced similar?
