What the heck..?

Peak positive opk was cycle day 15. That same day I had spotting when I peed twice (so slight I would have missed it if I weren’t looking for it) which made sense for ovulation. Well today I got the blazing positive at what I thought was 6-7 dpo 🤷🏻‍♀️ What the heck am I supposed to make of that..? Anyone ever have this happen and if so, what ended up being the cause?
