Will I Ever?

Today makes day 4 of no period and still negative tests. I think I'm cramping so AF might come today but idk if I'm stressing so much I'm giving myself abdominal cramps; this has happened in the past with my anxiety. I've been having trouble sleeping through the night the past week; just tossing and turning all night, night after night. All I can think about is wondering if I'm pregnant. And the dreams are always negative dreams of why I'm not pregnant. I'm exhausted and just want to be pregnant or get AF; please, no more guess work!
