Got the static smiley (peak fertility) on Clearblue advanced digital OPK, but the lines on the test stick look like this. I thought the line nearest the arrow had to be as dark/darker than the other for static smiley? Or am I wrong?
I tried to confirm with a cheapy OPK later that day and got something similar (image of this in post too). Did CB just read this wrong and actually there was no LH surge?
