Hi There. This Month I Got My Period During My

hi there. this month i got my period during my second day of the active pills on week 3. for me this isn't normal and my period always comes about 3-4 days after i take my active pills. Im not worried, because i understand this happens but my question is, right when my period stops( probably tmmrw) do i start my new pack ? or wait until next month ( feb 1)?
