Spotting concern pls help

Hey everyone, so ive been in bc for a few years. I do two packs then the 4 day break because i have pcos so i get less periods. I last started my period around the 1st of oct then started the new pack the next day then had my period for about a week. Ive been spotting brown since it ended. I usually spot like a day or two of brown after/before period but its been too long over a week of spotting. I took a preg test and it says im good but should i take another, go to dr, any advice?😬 also its the combination pill if that makes a difference
