IS THIS IMPLANTATION BLEEDING?

a few days ago i peed and wiped and had light pink discharge, now i wiped after peeing again this morning and this is what i see

according to my calendar i was supposed to get

my period on jan 31st. my last period was from jan 2-8 and i haven’t seen any period blood. i had PROTECTED sex once a week all throughout january and am confused as to how this is possible if it really is IB 😕

should i take a PT? or is it too early
