THREE DAYS AND THE SMILEY FACE STILL APPEARS ON MY STICK
Hi, I just started using ClearBlue Ovulation Digital sticks. I started on the day I was supposed to and my High Fertility (smstarted on friday and went on for 4 days, friday, saturday, sunday and monday, then on tuesday Peak Fertility (solid smiley face) was displayed on the stick. It's been two days since and the smiley face is still displaying on my stick...what does that mean? Is my stick defective?
