Should I take estrogen even if I 'Pass'?

Hey all, I'm fourteen years old right now and I am just wondering, because my dad has said I 'pass' and multiple people that I have told said they didn't even know, and I am not trying to like, be uppity about it, Its just If I 'pass' is there really a point in me taking estrogen? Oh, and I'm trying to make the case that I should go on it by the way, if that helps at all but that kind of stumped me.
