Off of BC and TTC - Please advise!

This is a bit long, but really need help! Please and thank you. :)

My husband and I decided to start TTC in August. My pill pack was due to end on August 10th, but I stopped taking my pills on the 7th and my period therefore started on the 10th (normal as far as I could tell). I used Glow to track my ovulation, and we BD several (probably 8+ times) around my expected ovulation date (August 25th). It’s now September 18th and I’ve had no period. I’m 11 days late according to Glow. I took a test on the 14th and it was negative.

My main question is, is it possible to still ovulate even though I’ve had no period yet? When would your estimate be that I would ovulate? I’m a little lost on when we should BD since I’ve had no period. Along those lines, I’d have no idea when to even test again since my period is MIA and it’s unclear when it will start. Any help is appreciated!
