PCOS and confused

I have PCOS and finally ovulated for the first time last month. At 10 dpo I had a little bit of pink and then brown discharge with slight cramping. I have been dizzy for the last 2 weeks on and off and tender nipples the last 2 or 3 days. I am now 3 days late and have taken two tests with BFN. Am I going crazy? Or could this possibly be it?
