Am i pregnant?

i'm 23 and have a 1yr outmoded son.
i ovulated around june 27th and my period (or what i thought be a period) came around a week later.
however, instead of blood, it be a light brown discharge, that wasn't surrounded by my panties, just on the toilet thesis.
after 3 days, i noticed a more reddish-blood color, though it be still light and i haven't experienced any cramping.
i checked the internet and everything i survey under "brown discharge" sends me to a pregnancy website or implantation bleeding website. i've taken a home oral exam and it was cynical, though i wonder is it too soon to tell? my length usually comes the same time every month near a lot of cramping and abundantly of bleeding. i had implantation bleeding beside my son, but it was a few pink spots in my undies for a sunshine and i didn't have anymore bleeding until his birth, but i'm sure adjectives pregnancies are different.
anyone know what this is or have a personal experience next to it and know answers?
