Before i test, could i be pregnant?

I started 2 days early (12 dpo) that was Friday night. I counted Saturday to be the first day only because I was spotting all night Friday. Well I should of got off Wednesday, but I stopped Monday-tuesday.. well all of a sudden yesterday I was spotting alot of brown discharge and today I've been spotting off and on light pink and now I have a little bloody mucus.. what could this mean? I'm getting really no signs of pregnancy 😭 but this period has just been way off.. I'm afraid to test til I know there would be a chance...

Any ideas?
