last 2 months have had my period twice a month. But this time it has started in 18 days. Although it is my second year only, i had normal cycle of 30 days (not exactly but from 27-32...i think) . Evenn though these months i've been travelling that wasnt super long distances and wasn't stressed or whatever. + i'm a virgin...i really don't know what's going on! getting scared about the fact that i might have some infection or??... please help me :-(
