With DS1 I'd woken at 2am with pressure down there that felt like i was busting to go to the toilet, which I thought was strange cause I'd only done my midnight pee less then an hour before. I sat on the toilet and it gushed- though i didn't realise it was my waters that had broken. It wasn't until my 2nd undie change that i realised i wasn't wetting myself with the remaining small trickle. After that my tummy shape had changed alot- it had really dropped and kinda deflated.
