Rachel, my first labour was quick and second time I had painful BH so was worried I wouldn't recognise labour. In the end I did, but only purely on instinct, and just as well I did as the labour was only 3 hours and I didn't make it to the hossy with much time to spare. My contractions were slightly stronger than BH and didn't stop when I rested. But they weren't any more regular than the BH and they didn't get closer, more regular or stronger until after I was at hossy (and I was already 5cms then and birthed about an hour later). So the only advice I can give you is go with your gut. Somehow I knew that this was different, hopefully that will happen for you too!
