Are Delayed Periods, Food Craving And Stomach Pain Signs Of Pregnancy?

I was suppose to start my period the 2nd of this month. Today is the 8th and still nothing. I took a home pregnancy test saturday and today but they were both negative. I plan on taking one in the morning just in case my levels of HCG are low. I have been craving excessive amounts of ice and I have low stomach pains. Is there a chance that I am pregnant even though I keep getting a negative test result?
