text: does it mean that u are less fertile if u dont have ur period? i am like 20 and i still havent gotten my period regulary i get it like once every acoulpe months  does that mean that i am less fertile when having sex  but rarely i would get it month to month like maybe twice i would say yes, it could mean that you are less fertile. one friends of mine had this problem too, doctors said she`d never get pregnant. yet she now has a 9 months-old sweet babay boy. best fo luck to you!
