I'm late! Is it just PCOS or should I test again?

Erika
So I have PCOS and we've been trying since October. I've always been right at 30 days since stopping birth control (except last month I was at 33 days). I took a digital test on day 35 and it was negative. Here I am Day 40 and still no af! Is af just not coming this month due to PCOS or should I test again?
