Need advice!! My younger sister is pregnant?

my younger sister is 19 and she is pregnant and she is going to have an abortion. im kind of trying to talk her out out it but it seems just like such a easy and covenant decision for her. I just want to know what its like from any women that have had one be for such as pain, and procedure that you have to go through and what damage it could do to her. It seems so easy for her to have the abortion I want to know more about it so maybe i can help talk her out of it
