9 days late

Isabel

Hi so idk if I should test again or not DONT want to get let down again but I am 9 days late. I have pcos my cycles are usually somewhere between 30-35 days this is the latest I’ve ever been I usually start my period by now if it’s late. I tested when I was 7 days late with fmu using frer and got a BFN! Going on year 3 ttc any thoughts? Has anyone ever tested positive this late?
