Is this weird?

I workout at least 5-6 times a week and I've noticed lately that my bottom pouch is very hard. Before it was soft so I figured it was just fat to get rid of but now it's hardened like its a big ab... It's not because it's round and I still look 2-3 months prego. Anyone experience this?
