Sorry to hear you are in a stall Andrea. They suck, but as long as you continue to do everything right the weight will start moving again.
Make sure you are eating enough, drinking enough, getting plenty of protein, and exercising if you can. For me, oddly, the way I broke a 4 week stall was when I had a sore throat/chest and had to stop running. I went on to lose 12lb in 2 weeks and that was 7 months post op.
Keep trucking hun. You are doing great.
