AF is late but BFN--is this PCOS?

Lauren
My husband says "keep waiting for horses not zebras" but AF is more than a week late and I still have a BFN. Have taken 3 Tests in the last week, to no avail. Now I'm worried it's PCOS or something. Doctor can't see me til Thursday and it's agony waiting. Did anyone have a BFN and turn up positive when they went to the doc? Or if you have PCOS, what were your symptoms? I've had longer cycles since i got off the pill 9 months ago but never more than 33 days... 😥
