Boomba - I've had it every time and it's never caused any issues during my labours. I'd suggest you get in a bath and stay there for as long as you can. I've done all 3 of mine in the bath and it was awesome. Delivering in the water wasn't an option for me unfortunately but I made the most of the bath and got out at the last minute either when my waters broke (and were always mec stained which meant I had to get straight out) or I was getting ready to push.
