Should I give up?

Jennifer

So today is my 7th day with a flashing smiley.. On the instructions it says to just stop testing after 9 smiley meaning you won't ovulate this cycle. Has anyone reached peak after so many flashing smiley? I don't know if I should just give up in a 2 days when I reach my 9? I know Glow is just a prediction but it says I won't ovulate until next Thursday! Should I keep testing in case?
