Did I miss my surge?

So I started tracking with my ovulation test the day after my period and they were all negative so I skipped 2 days and now I'm 2 days into my fertile week and the lines are getting lighter. I mean seriously light like almost not visible anymore. Could I have ovulated sooner and missed it those 2 days. It was 3 days after my period when I took a break to save my strips. Ugh I'm so mad at myself now.
