Bleeding but still have positive test . Help me !

Hey ladies ! So over the last week I got my bfp that was faint . I haven’t had a period in 3 months I have (pcos) and I decided to go to urgent care and they did bloodwork that said I was pregnant but the lady said I had a hcg level of 16.1. Which I thought was low . That day after work I got brown discharge tmi sorry! And the next day it seemed to be a lot heaver and red with brown somewhat. Now it’s more brown then red . Am I having a miscarriage?
