Ovulation

So I am in the process of TTC and for the first time this month I started using ovulation sticks and was surprised that the calendar on here has had my ovulation timing wrong for months now (🙄) but , once I finally got the surge line, I tested twice a day , once first thing in the morning , and right before bed. According to the stocks I have been ovulating for roughly 4 solid days now? Is that even possible? They says it’s usually at 12-48 window but can you ovulate first as long as the sticks are saying?

Here are the results , there were 3 more 100% positives but I stopped recording them because I was totally done doing the BD at that point lol.
