Weird period???

So I don’t have anyone to talk to so if you are able to answer this question please do.

I got my period a week ago, it was a normal period, i always have regular periods, but on friday (posting this sunday evening) i started to bleed again? And the bleeding just stopped (sunday evening). So my question is, does anyone know if that was just spotting in between or maybe an un-regular period or maybe implantation bleeding? I don’t know. Maybe someone can answer that’s had something like this before?
