Probably a really dumb question about my period.

Hey y'all so I've been spotting n light bleeding on n off for about a week now. Well my bleeding went away for 3 days and now its back like a full blown, normal period. I had a major clot when I wiped though. Is this normal? Or has anyone else expierienced something like this? Also, I have symptoms of PCOS but my Dr couldn't find any cysts.
