Missed period. Pregnancy symptoms. Negative tests?

-My period is 4 days late, I am very regular within one day of due date every month (except times I have been pregnant)

-Symptoms : Crying at the drop of a hat (I do not cry - this happened the last 2 pregnancies), crazy dreams, CM, the ribs at dinner tonight made me wanna throw up, I could not eat because I could smell them…Did I mention moody

-Very faint line on my first day on missed period, the rest have been negative…

-Not in a big hurry to have 3rd baby, but I would be ecstatic if I was pregnant. I want another!

Please please help me. I need your stories, please. I do not know whats wrong with me. I wish AF would just come if Im not pregnant lol
