Mom is in denial about my period?!

So, Im 13 and have been having problems with my period for over 2 years now. They last for at least a month at a time and very heavy. I kind of know for a fact that I have anemia because I have pica and I've had that for at least a year now. I've been asking my mom for over a year to take me to the hospital, doctor, ANYWHERE. (HINT: I've been asking for a year which is a very long time.) Yes, I have a father but I don't want to explain this to him it was hard to explain it to her. I was in band today and I play a woodwind and I couldn't play because I had no breath and felt like I was going to pass out. So I think it's getting more serious and should go to the hospital. She decided that my dad will take me when he gets home tonight. (at 1:30 am) I don't want him I want her to go but she won't. I don't know what to do. (NO THERE IS NO ONE ELSE I TRUST, LIKE, THAT CAN TAKE ME.)
