I worked with a young person whose baby had stopped growing at around 10 weeks, and when she bled at 14 weeks they gave her the tablets and sent her home. Similar to 4getmenot's friend, she had to go thorugh that at home, and then was still returned to hospital for blood transfusions, as she had lost so much. Make sure your friend is certain on dates, and firm with doctors (although I understand it's a sensitive time for her).
I don't know much about abortion, sorry.
