No ovulation after trigger?

👸Jen♋️ • 38👸 with 👨‍👩‍👦‍👦, and 5 👼 as well as a 🐶& 🐈
I took femara day 5-9. So i had my hcg trigger shot yesterday at 730pm and then took an opk today and still negative. Ive been doing them daily then today when it was still neg I took one again about 26 hrs post trigger still neg. i will test again tomorrow but is it possible to have a "big old egg" and not ovulate from the tigger shot?
