im aloud too drink alcohol just not too much but ovbiously when your at a party with no adults your going too drink a lot!.
And there's the difference between being an adult and child. And adults are supposed to be around to supervise children to make sure this sort of thing doesn't happen.
As for the discharge and the cramp- YOU NEED TO TELL YOUR DOCTOR. I'm not encouraging you for or against abortion either way, but I'm getting the impression that is what you may be leaning towards. If you do want to keep the baby, then you need to see a doctor right away. Cramping and bleeding may be nothing, or they may be a sign of something going wrong with the pregnancy. The sooner you speak with your mother and a doctor, the sooner you can start taking care of yourself- whether that means scheduling an abortion, learning about safe sex (or how about even abstinence?!) and responsible drinking or getting yourself some prenatal vitamins and making sure you're eating healthy and all that.
