Probably a stupid question but..

I monitor bbt cm and opk. I took a test yesterday and it wasn’t peak but it was almost there and now today they’re super light. Now my bbt doesn’t support ovulation yet and I generally ovulate cd 17-18 I’m on cd 15. I’m just freaking out a little thinking I missed it bc I did have ewcm a few days ago but I still do I usually have like a 4 day ewcm window when I’m ovulating. Maybe im just off or I had a random surge and it hasn’t happened yet. Anyone have something like this happen to them? Im going to carry on as I didn’t ovulate yet but will weds/thurs. I’m just freaking out a little lol
