Period on Depo?

Hannah

So I got the Depo shot back in October and am due for my next one in January. I have a lot of issues with cysts as well. All throughout this shot I have not gotten my period.

Thursday morning I woke up to quite possibly the worst pain I have ever felt followed by my period. I want this to end noooww.

Is this normal? I might need to go to the hospital I'm in so much pain.
