Confused about Cycle?

So before I started tracking my ovulation I always had 29-31 days cycles and assumed I ovulated somewhere in the middle of that. Pretty average. This month I tracked my ovulation and it said my peak was at CD9 and that I’d have a 23 or 24 day cycle. So now I’m 2 days late for that prediction but still not late according to what I knew as normals before opk.

Basically I’m confused. Do I go with the opk predicted cycle and say I’m 2 days late, or do I go with what is normal for me and expect my period in5 days and just assume I ovulate really early in my 30 day cycle?

Also, I took pregnancy tests at 10DPO, 12DPO and 13 DPO and they were all VERY negative.

Any thoughts on this?

Thanks!
