What is the youngest age you could get a hysterectomy?

I am a 15 year old girl and I am sick of having my period as it is an inconvenience I do not need. I never want children even after I get married when I'm older. I do not want to keep on having abortions if I do get married.. It would just be easier to get this done.Please don't say you'll change yor mind or bullshit like that because I am getting good grades in school and I plan to go to college and pursue my career. I have no interest in being a mother whatsoever. I know I sound like a selfish person , because I am. When is the soonest I could possibly get this procedure done? Thanks and sorry for the long paragraph
