Thank you LadyLove, that is reassuring for both scenarios. Yes it was a ClearBlue digital. I would have thought if I were to get a faint line on First Response on Tuesday, I should get a positive digital 4 days later? Without knowing when I ovulated it makes it really hard to do the calculations... The last time we BD was 19 days ago (14 days before the brown blood), so I'm hoping I O'd late & maybe it is still early.
