I've stalled a couple of times for a couple of weeks, even gained a pound once in three weeks, the other two I didn't lose anything, then the next week- BAM! I'd lose 5 pounds, and another time, 9 pounds. I have no clue why my body does this, but it happens more often than not in this weight loss journey.
I'd give it another week or two before making any changes. Your muscles could be holding onto water (I know this happened to me during my recent 9 pound loss) for a bit, and when it let's go, watch out scale!
Hang in there.
You have to remember, you will not lose every week- you might go two or three weeks without losing, then the pounds will start coming off again.
