can glow possibly be off by a week ovulation

So i’ve been tracking ovulation this month as this is our first month ttc. I was using the clear blue advanced opk and on the 6th i got a flashing smile i ran out by the 10th which glow assumed was my ovulation day but i still had a flashing smile and i know for peak it’s a stable smile. I also know i’m ovulating due to my cm bc it comes ABUNDANTLY. I started getting the egg white cm on the 10th but then it started coming out a lot by the 12th and now today it’s very watery and egg whites as well, could my ovulation be today? Would you recommended bd every other day for the next week to secure the date?

Also, yes, i know i can buy cheap ones to get an accurate date. I just get too much anxiety testing ovulation and thinking about all of this.
