Depo and cramping ?

Does anyone have depo and have cramping and nausea this is my first shot I got it in July and I'm not spotting or bleeding but i am super crampy and I have lower backache especially when I'm doing something like cleaning or walking is that normal on this birth control ? Has anyone had the same thing ?

I'm due for my next in October and after much researching I'm not getting it no more but I'm just wondering about this symptom as well as nausea when I asked a nurse she said nausea is not very common on the depo so now I'm like wondering what my nausea is from and the cramping
