Advice needed

So I was diagnosed with pcos last april. My husband and I tried this cycle. My period ended on Oct 24th and it was due Nov 18th. I’m currently two days late. I tested this morning at it was a bfn. I did experience brown spotting Nov 12th/13th. I’m not sure if it was ovulation bleeding or implantation bleeding. I have no idea what is going on. 😔
