Cramping after period

dark lord • Always down to bitch about my period with awesome humans. I like movies and art. I have three cats and am great at parties.
I stopped bleeding about two days ago but my right ovary(?) And lower back are still having dull cramps. This period was one of the worst ones I've had in about four years so I wonder if it has to do with my uterus producing too much prostaglandin. Anyone else experience and end up feeling fine in the end?
