Could I be pregnant?

Now I know the only 100% sure way to know for sure is a pregnancy test, but I need some other input. I have recently felt bloated and cramping my my abdominal area, and lower back. I have also has some nausea and also certain foods don't even remotely sound good. I am about a week late on my period and have still not gotten it. I was also late last month but did get my period.  Please no rude comments.
