Late ovulation? Help please!

Diana
My periods are usually 29-31 days, but this month it looks like I ovulated really late. What day do you think? I think cycle day 22 but Glow says day 20. I'm on cycle day 33 today and no sign of af. I took a test and it was negative. Am I 13dpo or 11dpo? Could it still be too early to get bpf?
​What do you think? Thanks!
