I have this feeling that I am pregnant, the last couple of days Ive felt just down right crappy?

the last couple of days I've had strange twinging cramps in my Mid section , down in my uterus, along with my feel heavy, achy today, I've had a head ache all day, hungry one minute , then once I take a couple bites of food i'm done, cant' eat any more. My s are swollen ever so slightly, Ive been extremely emotionally . My Intuition tells me something is up but do I listen to that Intuition- I know right now I can't take a hpt because I can't stand to see the BFN , so I know that I can only wait until Af is due at the first of the month . But am I crazy
