Im 26 yrs old. I started my period 12 days early. (my periods are always regular the most I started was 1 day early). I started cramping at the time of starting. Its been 2 days and no heavy period bleeding. Im now also having backacke and feeling a little quezzy. I rarley get cramping with my period and I never have back pain or feel queezy with my periods. Im not boated like I always is when I'm on my periods Im not on any birth control.
