I can't tell one from another myself, and they always look pretty roly-poly, especially in winter coats. There was a raccoon couple mating in my yard on February 1*, so around here that female is likely halfway or so through gestation, but our climate is quite different.

*They take ages. I'd no idea. I took a short video on my camera, went upstairs to figure out how to transfer said video to Facebook, which took a little time, came back, and they were still at it. Making out like bandits, as one says.
