Spotting 13dpo

I’m pregnant as of 11 dpo. I’ve taken three tests daily and the line is getting darker. I just spotted, it’s pink and some mucous. Enough to show up on a pad/when I wipe but not a ton.

I’m really scared I want this one to stick. I think spotted during my first pregnancy but I don’t remember when/how much. Anyone else have this? It does look distinctly different from how my period usually begins...
