Negative test but...

So I took a test Wednesday and a test Thursday both were negative, also went to the dr and they said negative... BUT I KEEP GETTING SICK and so is my husband I know it's crazy but I threw up last Saturday and also this morning my husband brought little Caesars home and had bread sticks he told me the breadsticks smelled like throw up (smelled like regular breadsticks to me and everyone else) and he said it made him want to throw up he was gagging and everything and my stomach has been feeling so queezy like never before. I'm dude for a period tomorrow and I have no symptoms but every month I know my period is coming because I have the symptoms 3-4 days before my period even arrives. I didn't know my period was even coming tomorrow until I checked my calendar... What do u ladies think?
