Am I pregnant!?!

Karina_

I missed my period in January I took a test and it said negative. I was told I had strep and an ear infection at the same time I took the test but I was put on antibiotics to get rid of my strep and ear infection. I just got off my period for the month of February.....but I am feeling super nauseous and moody! Could there be a chance I am pregnant???? Help!
