Have you ever had a month where you had no peak?

I've been using it the last few months and this month I still haven't gotten a peak reading (CD20) I usually get it CD17/18.

I had a solid smiley on CB advanced digital on CD 17 but never had any flashing smileys either. Wondfos were strongest at CD17 but definitely not the strongest I've seen them in prior months. (TY Anya for the free OPKs!!!)

I know sometimes pee tests aren't all that good to rely on, but being that it's been pretty good the last few months, I'm kind of confused why it's not picking up LH. Whether it's bad timing/monitor error, or if I'm not Oing this month. I don't temp (as I'm not very good at it) so I can't confirm if the CB test was right, but it is aligned to CM changes and previous months of peak on monitor.

Looking for any experiences. Help curb my TTC (in)sanity!

THANK YOU
