Been stuck at the same weight for over 3 months!

I just broke a 13 week plateau myself.  Oddly enough, it happened just after having fluid out - i was having allergy issues, got too tight, and had a cc removed.  Then i lost 4 pounds in 10 days, and it's stayed off for the last week.  I've not been a steady loser, ever, it tends to come in spurts.  Keep doing the right things, maybe step up your exercise, and it will start coming off again.
