Ok so i'm 11 days late for AF, and blood test was negative on 7 days late but the ultrasound said it's possibly pregnancy, and I have PCOS, so yesterday I started light bleeding brown and pink and today but no AF and the dr said to wait to test again for next week, do you think it's pregnancy or not?

PS: I've been regular regardless the PCOS and this is the first time it's this late with no PMS symptoms (which I always had) and very tired, nauseous, moody, and bloated.
