Period or not a period

Summer

I just got off the depo shot. It was due April 2nd and I didn’t go. April 3rd-10th I had a period. Then nothing afterwards. Not pregnant or anything. On July 23rd I had brown blood when I wiped, for a week and a few days, it was back and forth from brown to red. I had cramping with it. It stopped for about a week and now Its back to brown blood. The cramping hasn’t let up since the 23rd. What would this even be?
