Question - TMI

S

Okay so I know implantation bleeding is rare so I’m not clinging to it but I posted earlier and a few ladies mentioned it. Yesterday was 9dpo, I went home after work and I went to the bathroom and wiped and there was the slightest pink watery discharge. Put a liner on and it’s caught the tiniest bit of brown. Same today, slightly brown and watery when I wipe and a bit on my liner. If this was in fact implantation would it have been picked up on a blood test yesterday? My doc ordered a hormone panel for me and he threw in the hcg lab so I’m wondering if the test would tell me 🤷🏻‍♀️

Also if it was implantation would the implantation occurred yesterday since it was pink? And the brown is just the remainder today?
