When did I ovulate 🥲

HELP😅 The last few months I was doing much better at tracking but I took way less opks and really just relied on my Oura ring to track ovulation this month (we had a very busy month with lots of stress so tracking just wasn’t priority and I needed a break from the doctors..) but now I’m wondering when I actually ovulated 😵‍💫 I had a positive opk cycle day 13, and another positive opk cycle day 18..my temp did drop a bit on cycle day 14-15 so I thought that was ovulation then it rose for a few days BUT then it dropped again cycle day 19 before rising and staying elevated since ! Ovulated cycle day 18 last month. No period in sight.. if I ovulated earlier it’s due already.

Tests are negative, I had the tiniest bit of spotting two days ago now nothing. I’m so confused this month!!
