Did my thawed scallops go bad in the refrigerator after 2 days?

I am new to the world of seafood cooking. I bought a pound of scallops Monday afternoon that had been previously frozen...but I didn't cook them that night, and planned on cooking them tonight...2 days later, but they do have a SLIGHTLY funky smell, aside from the "fish" smell. I dont want to risk it, but I wanted to ask others who know about this stuff. Thank you in advance for your answers!!
