Some women just naturally menstruate on a very frequent basis, there's nothing wrong with you at all. There are certain birth control pills that will regulate a period. There's two or three brands that makes it so you only menstruate once a year even. Go ask your doctor about getting on birth control, lots of women take them just for regulating their period.
