Abnormal for me FREAKKNG OUT

Okay so I need input! I started my period today 5 days early. I have never been early in my life. Since the first of the month I have had intercourse 7 times. We always use the pullout method but that's it. The flow and everything isn't normal either and I have cramping but normally never cramp. And had no other signs leading up to a "period" either. Anyone have any ideas or thoughts as to whether I could be pregnant? Willing to give more info if needed
