Very odd, I could have sworn I read a response from Tracey on this question. Yesterday or early this morning.
she said something about how it's different for everyone and that some people pass them on day 1 and others dont pass them until after they start eating (after MC) but still taking the B&P.
It's strange that it's not here now, but she talked about it for sure. ((Unless I'm going crazy!))

My opinion is that it all depends. I personally have only had what looked like lining pass once in all my fasts, but this is the first with B&P, only B before. Good luck.
