I started my period today, 2 1/2 weeks early before my next expected period. I have all the normal signs like it is a normal period. (gas and slight tummy ache) I have been having lower stomache pains, like really bad cramps this past week. I almost thought it could have been a kidney stone. Yesterday the pain was gone and today I woke up with blood! Scared the living crap out of me!... I am 21 and have had my period for six years now. I have never had one this early. The earliest they have arrived is maybe a week early. It has only been 10 days since my last period!!! Am I pregnant?/Were pregnant?/Is it just a period?

Additional information: I just recently took a pregnancy test a few days before my last period. It was negative and I ended up starting a few days early.
the blood i saw this morning is more like HEAVY day period blood
