Sandy.... my theory on pee....ing... is this.... From a sanity point of view...... if i keep POAS and I get BFN..... and then AF arrives... then i m like... ohhh ok well i have been getting negatives....it is better for my head than to be stressing out waiting to POAS on the exact date only to have a BFN...... If I keep peein and it keeps going BFN... and AF still doesnt arrive.. who knows .. it may just end up BFP....

So in my round about way I hope that makes sense
