I agree with Pee - you really don't care when you're in the middle of labour and you may even find that you WANT them to examine you so that you know how far you have dilated to give you a bit of an idea as to where you're at and the will to keep going! LOL

I only got to 9cm and it was quite a long process and I wanted them to examine me so that I could feel like I was getting somewhere for all the pain I was having!!
