Short luteal phase???

Question... sorry long

I am soooo confused. TTC since May. I thought I was just starting to learn my ovulation based on my body signals (CM etc.). We finally went to a specialist since it has been 6-mo and I am 39 y.o. I immediately had blood testing for LH, FSH, & AMH. My numbers weren't all that promising. I had the HSG exam on 11/14 and that was all good. I had an ultrasound on 11/16 that showed two follicles on each side that Dr. wanted to watch to see if they would grow. Had another ultrasound 11/19 (CD 16) and the follicles had grown to 19mm & 18mm. The doc scheduled me to come back 11/21 for another U.S. with the plan to administer trigger shot. When I went the U.S. showed I had already released eggs on my own....

***so that had to be 19th after my appt or on 20th just likely right???

***So if I released/ovulated lets say on the 20th... today would be 8DPO right???

AF is due tomorrow (CD 26-which I have been regularly since I stopped BC in April).

***Is it normal to not have that many DPOs before AF???

All the apps I use predicted ovulation 11th-17th .. if I always have way later maybe that's why we have had trouble. I have never used any OPKs or anything.

***Help... any insight??? Did we miss our window of opportunity or do I still have a chance at BFP???
