Help please, really worried and confused

Emma

Hi everyone, so this is my third cycle TTC. This week I’ve had days of flashing smileys, glow and Ovia have been spot on so far with my periods and ovulation. Except for now, I was supposed to ovulate yesterday but still had a flashing smiley. Today, I got up and had a smear of brown mucus, but still a flashing smiley on my OPK. What does this mean?! Thanks for any advice you can give x
