Haha Emma, you'll go broke AND drive yourself mad like me! Silly me started to pee on the stick 3 days post transfer and the pee stick had the second faint line which was the left over trigger in my system. It disappeared when I peeed 6 days post transfer and then I got the proper second line 8 days post transfer. I guess I freaked my DF out about how many tests I've done in my last cycle because he's already asked me if I was going to do the same as last time. Poor bugger, he thinks I'm beyond help and mad! If you really want to POAS, I'd do it 8 days post transfer to be on the safe side.
