Cramps after period

Okay guys, I was wondering if you could help me. I recent came off my period, I had the usual cramping before and during but since I’ve came off my period I’ve had period like cramps and bloating. I’ve done tests and they’re all negative so I am definitely not pregnant I never usually get cramping after my periods. What could it be? Would it be worth checking in with my Dr to see what he says?
