No Solid Smiley and Error Symbols
I am using the Clear Blue Advanced Ovulation Test. This is the second month I've used it. Both months I receive a flashing smiley face at least 2 days in a row. This month I tested Friday-flashing smiley, Saturday-flashing smiley, and this morning the book symbol was present. Is it normal to skip the regular smiley? And why did I get the error symbol?
