Confused

Terri • 27 happily Married 💍. Daycare teacher. Canadian Newfie

So I’m taking femera 5 mg after the first three months on 2.5 mg failed. My fertile window would always start around the 14. And I would ovulate around the 23. (Confirmed with opks ). Today is cycle day 14 and I’ve tested twice today and my clear blue digital advanced opk is a circle meaning not fertile .. anyone else’s cycle change taking a higher dosage ? Could I have already ovulated ?
