i already had it this month from the 8th - 13th .. and i just got it again last night o.O is this bad? cause i thought you only have it once a month ?? :/

no, not really. you can also get it early due to the month of February. which can count as once a month cause january is ending plus your period from 8-13 only last four days. usually most periods last for a week.

haha okay. i feel better now x)
isnt there a specific # of how many days apart your period are? 21 isnt it? or maybe im thinking of something else? =/

Your menstrual cycle is usually 28 days apart. Sometimes it fluctuates and if it doesn't go too crazy then you shouldn't have to worry. Sometimes I don't get mine for a looooooong time (in that period I might have like 1 day of a really light one), then when I get it it's super heavy and past a week. That rarely happens though. Your periods could fluctuate for any number of reasons, including stress, weight gain or loss, etc.

^That & your period can be irregular for a while when you first get it. When did you get your first period?
