I'm scared. please help.

I have a lot of unprotected sex. And today I passed out because I got nervous that eve said I should've started my period 4 days ago. But last month I started my period on the 26th and today is the 23rd.I have been getting the same symptoms as I do when I'm on my period ( bigger Breast, pimples, bloating in the stomach, and REALLY bad cramps.) should I be worried that I'm pregnant or am I just paranoid?
