I think you notice them more with second pgs Sarah. I certainly did. I had really painful ones with Tom, in fact a few times I actually started timing them they were so strong. Tom was early and a fast labour, but I don't know how much the BH had to do with that, I suspect it was unrelated. But you never know, they could help you have an easier and quicker labour. And I was worried about knowing when it was real labour, but when the time came, I knew!
