What can be the damage by now wearing a sports bra?

[2~Cute-as-pie~2]

I'm 14 and have an A size womens bra. Just wondering if I am doing damage by running and not wearing one.
I have one, but I cant be bothered using it sometimes
Thanks!
Sorry, I mean NOT wearing one

no damage I read that a sports bra during working out can help your boobs not to sag latter down the road.
