I usually just wait until AF shows up. This last cycle I got a little out of control and started POAS early... and wasted three FRERs. Dont want to keep that habit up!
Is it worth it to buy the ICs? So often I see people say that they got a - or a + on the IC but that they should run out and buy something more reliable. So if that is in the back of your mind, do you really even believe the results from the IC?
