I'm 12 and I've had discharge for about 7 months and I hate it in my underwear it's gross and I want panti liners but how do I tell my mom and one more thing about when do you think I will have my period I have some pubic hair no armpit hair I wear a size 32 a bra and my mom had hers when she was 14

Just talk to your mom about this... trust me... she is the person to talk to about this.

And as far as to when you get your period... thats hard for anyone to guess, as it cold be as early as the next few weeks.or as long as the next few years. Everyone is different.

Your mother hasn't noticed the discharge in your underwear? Who does your laundry?

Your mother has undoubtedly either experienced this herself or heard about it. She's the one to talk to. Do you have problems explaining yourself to her?
