So yesterday I got my first ever fixed smiley (dual hormone) in the year we've been trying. I was so excited and late for work that I left the stick in the device and tucked it away to show DP later. Now usually in the past, if I left the stick in the device, it was just switch off until I ejected later. But when I got back, the smiley was still there and stay there even when I ejected the stick... And left it for a few hours.
Now I'm worried that it was a false smiley. Anyone else had this?
