Of course you can ask - I think most of us love to talk about anything related to TTC around here!
Last cycle I managed to get a BFP a bit sooner than usual but it was still a few days after AF was due to arrive. I had been spotting for a few days already by that time and the spotting eventually turned into a full AF. My recorded betas only got as high as 36 :-( The BFP only showed up on a FRER, my $stores were just showing thick grey evap lines.
With DD1 & DD2, I got my BFPs at almost 6 weeks along (my cycles are usually 28-29 days). Both times I had what I thought was a full 4 day light AF almost 2 weeks before the BFP. With DD1, I got my BFP and then the very next day MS showed up (my husband joked that I was making it up!). No symptoms before then. With DD2, I was only using $stores at the time and I think I might have got a BFP sooner if I had invested in some FRERs. No obvious symptoms then either, although if I was symptom spotting I'm sure I would have suspected some things.
Do you get late BFPs too?
