If I promise that this isn't going to be an 'is this it thread'...
Am pg with ds3/dd1, had no braxton hicks with ds1 and confused braxton hicks with ds2 as onset of real labour, went to hospital and even fooled one MW into thinking I was in labour.
Am getting stranges twinges at the bottom of my bump, quite regular, slightly painful but nothing that takes my breath away, also the odd sharpish pain is lower back. Does this sound like BH to you?
