I have very regular periods, usually every 28 days on the nose... Had mostly normal period this month but have been so emotional lately. I cry about anything!! Not feeling depressed or anything like that. Also have breast tenderness, could it possible that I could be pregnant anyway?

The only way to find out is to get a test done. Those are symptoms of being pregnant, but they are also similar symptoms of what happens before and/or after a cycle.

The symptoms are abnormal for me, that's why I thought maybe I could be.

Well if your having unprotected sex or a condom has failed then its possible, get a test done then u will know
