implantation or not?

So my period is one day late. 😂I tested this morning and it was negative….., but I’m having this weird light pink discharge, but I’m not having actual bleeding. Could this be implantation? it’s mixed with clear discharge. i had sex on october 21. it’s not getting heavier or anything and it’s not progressing to any blood it’s also not getting darker so I’m very confused. My last period was October 3, but I didn’t have sex until the 21st like I said.. I know this can’t be my period because I have very heavy periods and it comes and goes through out the day. no dark or bright red blood. only this….

I’m thinking maybe I just tested too early ? should i wait another week? maybe by the 5th should i test? i’m also having very slight cramping it’s kinda dull. my cramps are a million times worse than this when i have my period so i am

super confused.

thanks
