Ovulation tests problems 👎

So I’m due to ovulate today says the fit bit app. But all ovulation tests I’ve taken last cpl wks look negative 😳 I had ewcm on Friday but the ovulation test was still mid pink not dark or matching. I’ve yet to have a dark pink positive this month. My fertile window closes tomorrow and I have no idea if I’ve even ovulated at all 😩 all of these ovulation tests are negatives aren’t they? Top one is Fridays when I had lots of ewcm. 2nd one is last night and the bottom is today’s and today was supposed to be ovulation day! I don’t know what’s going on
