Should I get fake boobs or stuff my bra?

I am 14, and I'm TOTALLY flat chested. Seriously, there is nothing there. I even had my period already! (I got it when I was 13) Should I just take the bullying about my body and keep walking around with no boobs, or should I get fake ones? If you think I should, then should I get fake ones or et a bra and stuff it?
