What does it means if u have two periods in one month?

i'm 21 and usually my periods or normal but this month i got my period on the 1st and it lasted until the 6th but then i got it again on the 28th i never had this happen to me so what does that mean??What does it means if u have two periods in one month?
That is completely normal. Your period can last anywhere from 21-35 days..the average is 28 ( from the first day of one period to the first day of the next ) This happens to me on occasion as well. I usually blame it on the fact that Feb. is a short month..so I got my period in the first week of March ( instead of the last week of Feb ) and then again in the last week of March ( 28 days later ). No worries !
its no big deal. it just means your still working a few kinks out. if u really think its serious than see a docter
You just need to see you obgyn, they can give you birth control to take to help regulate your period!! And check you out for other problems like hormones and stuff!! Just be sure to see your doctor about this cause you shouldn't have two periods in one month. It can happpen but you may need some medicine for it or hormone pills and get checked to make sure all is well with you !! good luck !
It means you should see a gynecologist. You could have cysts.
its nothing bad...its normal for a girl to have that dont worry about it but if u are really are concerned...go c your doc. but i say its nothing big :D
