I'm due with dc4 in 6 weeks. With dcs 1 and 2 I had epidurals. With dc3 I had gas and air. I think I needed to push for quite a while but didn't realise it and I think I would have given birth far quicker had I realised. I labour quickly and was 3cm. Dh and I were left for about an hour, I should have realised really as contractions were every 2 minutes and lasting one minute, and I had a very heavy 'open' feeling which I now realise was ds's head. I did keep making grunting noises which I couldn't help but kept breathing away. Midwife came back after an hour and realised that things were imminent and I pushed DS out in 3 contractions. I think I could have skipped that hour of painful contractions if I'd realised what was going on.
Sorry this is rambly but I'm hoping to be more aware this time and listen to my body more. Just wondered about others experiences really
