You could play scrum half if you can think on your feet. The scrum half does not take part in the scrum but gets the ball if his/her team wins the scrum and then passes it to someone. A scrum half must be able to pass accurately, quickly, and to the right person. Try different positions during practice and see which one you are good at.
It really depends you could be forward or back it depends on how strong or tall the rest of your team is eg. I'm young short strong fairly fast I play winger and I'm 15 5'2 120 pounds and female
Maybe Outside Center (Back).
