I'm 13 years old and I just got this dark red and brown discharge in my underwear. It had stopped after that day and it like only happens for one day and then goes away. It's happened before but I'm kinda concerned. What is it? I haven't had my period yet but I am developed. I've grown breasts and I have hair down there,in my armpits,and some black leg hair. All my friends have had theirs but I haven't. I'm scared to talk to my mom about it because it's awkward and she doesn't really explain puberty that well. I need to know what this is. I've looked it up on the Internet and its talking about pregnancy and there is NO WAY I am pregnant. Please someone help me.
