Implantation bleeding? Help!

Ahh! Help please! Okay.. so I’m 1 dpo-according to this app and just generally following my cycle. First day of my Lmp was on 7/19.

Could this be implantation bleeding?

Dtd 2x in my fertile window this cycle and I’d be excited to be expecting ☺️👍.. has anyone else had something like this?

I did not have this with my other pregnancies.

Thank so much!!
