Why am I having 2 periods in 1 month, for the second month in a row?

This is the second month in a row that I have had 2 periods. This is new to me, I always have one a month but not 2. Has anyone had this happen before?Why am I having 2 periods in 1 month, for the second month in a row?
wow, u could probably be under stress, and u r losing a lot of blood, therefore u should seek a doctor n ask for some iron tablets. u could also have fibroids in ur uterus. get help soon.
Not to me. May be you have a split personality.
Every woman's body is different..Two a month is not a big deal..Mine runs the same way with two a month..
