Did I miss it??

I track my ovulation with OPKs regularly (take 2-3/day) and have a regular cycle. Usually I get a positive for 2 days when I am ovulating. This month, however, I was getting ready to peak and I skipped when I would usually check it simply because I was out and about. The next time I checked, the lines were getting fainter. Did I miss it over 12hrs? 😞😞😞 TCC 9 months now
