4 Days Late , Pregnant or Stressed ?🤦🏻‍♂️

on august 19 me and my boyfriend fucked .. (unprotected; withdraw/ pullout ) everything was good till i went home. i peed and at the end of my pee i felt something come out. i went into my room and grabbed a mirror and looked

this picture isn’t mine, i got it off google but this is almost exactly what it looked like except a lot more. could it have been my discharge?

also my boyfriend is good at pulling out so i’m sure it wasnt his.

ALSO,

a couple hours before this i had cleaned up because i knew we were going to get to business and my cm looked EXACTLY like this

my period was suppose to come saturday sep 1 or sunday sep 2

it is now wednesday sep 5 and still no period.

i took a pregnancy test monday sep 3 and both came out negative

what should i do?

why do y’all think happened aug 19?

could i be pregnant?

or do y’all think i am just over thinking me being late and is delaying my period even more?

pleaseeee help.. and no rude comments please
