Is an abortion the right choice?

I recently learned i have become pregnant. I did some research and am still fairly early (under 4 weeks gestation) would the abortion pill be fitting to use? I am against abortion but I feel it is the right thing to do only because I have a heart condition in which carrying with result in death for myself and the baby. I live in PA and am above the legal age of 18 do i still need parental consent/approval? Anything can help and the sooner i can act the better and safer, any other options are openly accepted as well. Please this is crucial in my life and i want to be as justified as possible.
