Not even sure I ovulated this month?

So here’s the deall we’ve been TTC for about 3 months with no luck, I started taking opk’s two months ago to track ovulation day which was going well.

When I took my opk December I took them later than I normally would in my cycle and got all negatives, is it possible I ovulated earlier than I thought?
