For those of you who planned your TTC journey and had to go off BC, do you recall how long it was between your last pack of BC and your first period off BC?

I've always been regular on BC and used to spot even just missing a pill by a few hours. My last period started on 10/18/11 and lasted the usual four/five days. Today is 11/23/11 I am 10 days late per my usual cycle (avging a 36 day cycle today).

I've gotten the BFNs and don't "feel" pregnant. Just wondering if I just keep waiting? How long should I wait for it?
