REALLY NEED ADVICE

Stopped taking my bc in August it was the pill form, had the 4 day withdraw bleed after that but nothing since untill this week on Friday I finally got my period but it ended yesterday which is a normal period for me well half way thru today I peed and when I wiped there was a good amount of red blood , now nothing again , should I take a pregnancy test . I know it's impossible almost since I had a decent bleeding period just really want to hear everyone's thoughts.
