Confused/help with thoughts on LH

Do any of these tests even look positive?? FF and Ava say I ovulated CD 13/14. But physically felt more like I ovulated CD 10/11. I thought maybe I had ewcm on CD 11, but it looked clearer/stickier. Even when I did the automatic detection in the FF app, on CD 11 it came out as “high” but I’ve had darker lines before so I adjusted it. 🤷🏽‍♀️

Then on Sunday CD 17, I had some dark spotting, just in the morning when I wiped. So I was hoping it was implantation bleeding. But hoping is not something I want to get invested in yet. 🤦🏽‍♀️🤦🏽‍♀️

I’m thinking that I maybe just didn’t ovulate this cycle with all this discrepancy. (2 years TTC, 1 MC 12/4/20)

thanks for any help!
