Cycle day 46 and still no period, I am 15 and my periods have been irregular in the past but I think since September they have been regular so I'm abit confused as to why I am late. There is no way I am pregnant as I am not sexually active, however I have been stressed a lot lately and a few people have told me that can affect it. I am one of the lucky ones in a way to where I experience no pain whatsoever so I can't really tell when I'm near my period until it starts, so therefor I've had no signs but that's normal for me. Does anyone know what can affect your period and make it late?
