So pissed!

I just got the depo shot in hopes it would stop my period. Well I'm going on day 9 on my period. I've heard women say the depo gave them 3 month long periods and I'm scared now that's gonna be me. Has anyone ever had the depo and it only gave them one period? I'm hoping my body is just adjusting and I won't have periods after this one. I'm so aggravated!
