I got my period on September first and I am still on bleeding, last time it was irregular too but not as long. It's not heavy, between light and medium. And It's on and off. I got my period this summe and haven't gotten it more then 6-7 times so maybe that could be why, first few years are irregular. And I'm still growing, being 13. Should I tell my mom or is that this normal? Please list all the possibilities.
