Ovulation confusion?


I posted this a few days ago but didn't get any insight.

I went to a new doctor this week who did an ultrasound on my ovaries. I have pcos so there were many follicles but one was much larger and he said it looked like I was about to ovulate based on the way it looked and he saw I had ewcm. This was CD 25!

This was surprising because I had been taking opks and tracking everything and along with that, Glow, Ovia, and FF had my fertile window a week earlier.

My darkest opk was on CD 18 and my BBT seemed consistent with that.

Now I feel like I can't trust anything! We've been having sex every other day since my doctor said that but I'm frustrated.

Has this happened to anyone else? I wish I could go to the doctor everyday to ask for an ultrasound.

If this happened to you, how would you feel about your predicted fertile window? Help!
