Am I Pregnant With Irregular And Heavy Spotting?

I spotted two weeks after my period last month, i am now two weeks late this month with signs and symptoms of being pregnant. Yesterday i started bleeding lightly (almost like spotting) but, it's not my normal period. It has been alittle heavier today but not by much. It's lighter than usual, and i still "feel pregnant". I am stuck and not sure what to think. Can you help me?
