Well, you can't have a stall yet
A stall is 4 weeks with no inches or pounds lost.
Two things - go back over your menu to make sure you're not overlooking something and a lot of people experience a 'post-Induction hesitation' about 3-5 weeks in, even doing everything by the book.
Make sure you've not added anything back in you shouldn't have and that you're still watching measurements, then just sit back and keep doing that. It'll start moving again.
Also, take your measurements now, if you haven't already. I lost a full dress size without dropping a pound, at one point.
