is it harder to get pregnant with longer cycles?

I am day 35 and still not come on and i dont think i will for another few days at least. So i must be having around 40 day cycles now as that seems to be the case since i have been paying attention to my cycles ttc. Is it harder to get pregnant? I feel so sad this morning and worried that this may not happen for me. I also have polycistic ovaries. But not the syndrome. Anyone out there with longer cycles have any positive news?
