Something like this! I’ve never used them but I hear people love them.
I’m glad you were able to recover the ring! Mine has gotten loose, as well. I ordered some of these ring size adjuster spirals, and they work well.

Weight loss is weird. I’ve lost around 50 lbs in the past year to get back to my pre-pregnancy weight, but it still feels super abstract. When I look in the mirror, I still feel like I look the same as I did before losing weight. Yet I’m back in my smallest jeans, so I have to force myself to believe I’ve actually lost weight. It takes our brains forever to catch up.
