a sign?

I coughed yesterday and threw up, luckily i was over a toilet, but two weeks ago I have mild cramping (no bleeding) & I've had sore breasts, mild headaches, frequent urination. plus yesterday I ate some smoked sausage & I didn't really like them. (normally LOVE them.) AF was due yesterday. I don't want to test and get a BFN again. we've been TTC since august.
