OP here! The ring had always been so tight that I couldn't get it off, but I guess loosing baby weight combined with the cold weather, my finger shrunk enough. I agree with commenters... I found it extremely odd that I didn't notice... Maybe a case of missing limb syndrome but with a ring? Anyhow, after spending a morning raking the leaves in freezing rain, I FOUND IT! An FML win! (Oh, and #55 sleet does freeze leaves when you live in Texas and the ground is warm enough to melt the sleet but the wind cold enough to re-freeze it. But we can compromise and say we are both right because it has been alternating between freezing rain and sleet for a little while now). WIN!
