Thanks for the reply Kim, pretty sure they are the early detection ones ( i have thrown the packet away!) Big absorbant tip with pink plastic lid thingy you put back on. Glad to hear you dont necessarily need to have a difference on two consecutive days to end up with a BFP. I was a bit bummed coz i thought it should have come up pretty obvious today if yesterday was really faint. Will test again tomorrow if AF doesn't show (and i thought waiting a whole 24hrs after yesterday morning was tough )
