weight loss

so, I gained 32 lbs with my second pregnancy. I lost 18 lbs within the first 2 weeks. I've been stuck at the same weight since then... I'm 8 weeks pp. however, I have noticed that I can button (not comfortably, but button) my pre pregnancy jeans now, and I couldn't do that 4 weeks ago...strange. those of you with similar situations, how soon did you actually start dropping lbs?? it took me 7 months to lose it with baby #1, but I don't remember stalling for so long!
