Cramping?

Ch

I gave birth about 6 weeks ago and directly after giving birth I was to choose a birth control to be put on. I was put on the depo 24 hours after giving birth.

I had an obgyn appointment to follow up with how my body was healing after birth about 4 weeks after and she said my cervix was closed and everything was fine.

Today I started to have some cramping on the side. I rarely ever get cramping anymore and I'm wondering if it could be from the birth control possibly giving me cyst and one could be popping. I do have pcos but I often never feel any cramping whatsoever. Thoughts?
