How do you abort a baby at the age of fifteen without consulting a doctor?

The only safe and legal way to do this is by seeing a doctor. If the problem is money or that you can not tell your parents there are legal ways around that. For funding you goto fundabortionnow.org and click on your state. There are private funds that can help you pay. For the parental consent you can ask for a judicial bypass at the clinic. That means a judge will give you permission. You find all clinics at abortion.com. Attempting aboriton on your own is both unsafe and does usually not work. This is why it is legal today.
