ok so i had my period october 5-11, i then just had it from november 2-6 which i had no signs of anything, no cramps no nothing which is very unusual for me. i then got the cramping the following week and had my period again from nov 14-17. this is just very odd for me. does anyone know what this could mean?

Anything could trigger a normally regular period to go crazy. Any changes in diet, or any extra stress or anything? I guess if it continues to happen you should see your doctor but 1 extra period is just a sign that maybe something that your body is used to has suddenly changed- an increase or decrease in your level of exercise can trigger it too.
