Can you get a late positive test if you have PCOS?

PCOS usually delays ovulation which would then cause a delayed period or a late positive (later than you expected)

In a sense I did. I always had fairly regular periods but with slightly longer cycles. I never tested for ovulation but I assumed that I ovulated in the middle of my longer cycle. That wasn’t the case and my ovulation was much later, like day 19-21. I got pregnant by pure chance because we had sex later in the cycle. I tested and got vvvvvvvvfl and didn’t really understand. Then tested a week later and had bfp. So in a sense a late positive, but more because ovulation wasn’t when I thought it was. Hope that helps!
