Early but feeling hopeful

Currently at CD 22.

Little TMI... DH and I were feeling a little frisky earlier. We got a little busy and at one point he pulled out to swap to a new position. We noticed a little blood on him so we took it to the shower. That was a few hours ago. I put my cup in after our bit of fun in the shower. I recently checked it and nothing.

I'm feeling hopeful that after a year and a half of trying, that this might be it. I've never had anything less than 26 CD. The random 68 CD in the following picture's (I use 2 apps to help track my cycle) is because I went vegan at the beginning of the year and it sent my body for a small loop. Lately my cycle has been regular.

Any possibility that this is implantation...? Or AF showing her ugly face early?
