Did I already ovulate?

Bliss

So I've been tracking my ovulation, and I got a peak and thought that I'd ovulate 12-36 hours after. So we bd. I got what the app says a positive two time after. I'm not sure if it was maybe bc of the time it was take or what. And now their fading back to negative, but my app keeps changing saying that I ovulate in one day then goes to 2 days so I'm really lost someone help.?!?
