Pregnancy or just my PCOS

A few days ago I posted what seemed to my a possible positive pregnancy test, well in now 11 dpo and this very negative. My periods are normally a few days early to a week early every other month. This month I had very very light spotting for a day and then nothing. My period still hasn’t started but my emotions are everywhere, I’m exhausted all the time and very nervous. I do have PCOS but it’s be been having good periods every month. Am I stressing myself out wanting to be pregnant but at the same time not wanting to be?
