Am i pregnant lol

So I have PCOS and was TTC but I gave up. All of a sudden, my cycle regulated and it was good for a while and now I missed a period and I can't eat anything but a few bites of salad. Greasy things make me feel so nauseous its not even funny. All I want is ice, water, pickle juice, and anything lemon flavored (like water and Italian flavored ice) its been a week tomorrow and its killing me. Before that I also had cramping in my lower stomach like I was about to start my period.
