Confusion about ovulation

Okay so want to start off by saying I have a superrrrr normal 27/28 day cycle always unless like stress and stuff it’ll push it to around 30 day cycle.

Last month I had my peak at CD13 and likely ovulated next day —

However this month, I only got a .77 as the highest for OPK and it didn’t show peak and my CM wasn’t as much but

Starting last night CD14 and just now CD15 I had more CM sticky more egg whiteish is it likely I am ovulating now ? And it’s not picking up on opk..?

Help please!!
