Test line lighter today

***ETA*** I know these aren’t positive. According to the app I’m due to ovulate on CD 16. Today is CD 14. I was assuming they’d get darker as ovulation approaches but it’s getting lighter instead. I’m only testing once per day this month bc I don’t want to use up all my tests when I’m not even TTC until next month.

Hey guys! My test line is lighter today than yesterday. I’m not supposed to ovulate for a few more days. Is this normal or did I ovulate early (before I started testing) and completely miss it? I won’t be heartbroken if I missed it. Not trying until next month. Just want to get a baseline so I can REALLY time things perfectly next month. Also, do these tests suck? They’re the Target brand Up & Up. Do you recommend a different brand?
