Am I pregnant?

My periods are always normal. I started my period and it only lasted one day and it was also a few days early. I'm having cramping that kinda feels like period cramps. I keep getting really bad head aches and it seems like it's hard for me to stay awake.  I took a test and it was negative. Could I still be preg?
