yep ring the hospital to just let them know whats happening, always best to keep them in the loop...

Its sounds like it could just be BH, but you never do know... I know it so hard when everyone tells you that you will know when its something more, but believe me you will...

I was once told that if your unsure take a panadol or something simlier for the pain if the pain goes away then its BH...

but other than that the very Best of luck as it sounds like very soon you will have you little ones with you...
