Flashy smily face

Amanda • Ttc#2 for a long time now got glow app in feb mid cycle I really want a fall baby so I`m making every effort next month
First whole month on glow after ttc for almost 2 yrs using other apps and opks. This month I bought the advanced clearblue digital decided to start testing early the box said to start on the 22. I started the 17th and today got a flashing smily. So this is earlier then I thought. The advanced gives 2 extra days right?
