should I be concerned?

Sarah 👶🏻👶🏻
Last month on BC was July, had a normal but heavy period in August, normal period in September and then no period in October, November or December. Finally got my period last week (January 18) and it's still going 8 days later. It was light brown spotting for a couple of days, I would get a couple gushes of red blood for a couple of days but never enough to fill up a tampon. Is this normal? Can anyone else relate?
