Is this my period?

I’ve had pregnancy symptoms and if i was pregnant, i would only be like 4 weeks. My period was a day late and then the first day it started and stopped at once, it was just a tiny bit. Today i had dark brown mucus discharge when i wiped, along with a teeny bit of blood. This never happens with my body, as i take the pill to control my periods and stuff. would this somehow be implantation bleeding even though i’ve already had symptoms? could this be a sign of pregnancy or is this just a weird period?

p.s. i can’t get a test until tomorrow so i’m just worrying.
