is this normal?

had sex like 4 days ago maybe and the first pic is the day after then the next photo is today (like a day or 2 apart from the last pic) and i listed where i am on my period tracker. idk if this is normal or not, i know the first pic is normal because u can bleed a little hit after sex w the discharge but this other pic idk... help? does this happen to y’all? it’s really just blood mixed w discharge
