Weird weight loss

I’ve been using the urge jar and it’s helped me to stick to my protocol. I’ve lost a total of 12 pounds. Last December I had to go buy bigger pants because my size 10s were too tight. I could wear them but the love handles were a bit too much to take. Now I’ve lost 12 pounds and I weigh less than I have for 8 years, but I’m still in the size 12 pants. Yes some of my size 10s are fitting better, but I also still have some that I can’t wear and the 12s are not really even loose. Last time I weighed this much I was in a size 6/8. What gives? I’m doing okay so far not letting it mean anything, knowing that I am on the right track to losing all the weight I want whenever I want, but I’m wondering if there is some kind of scientific explanation. It seems far more typical for people to fit into a smaller size before the scale moves rather than the other way around. I’d love to know that I can expect a “woosh” and wake up in a size 8 some day.
