Weight loss plateau and now starting to gain a couple pounds

[Crissy A 13]

I need any and all advise. I am 9 months post op. I lost 35 pounds and then nothing! I haven't changed my eating habits and even with fills I've stopped losing weight. I walk approximately 10,000 steps a day. No carbs. Has any one else experienced this? If so what should I do to boost my weight loss again? I was thinking to only do Protein Shakes for a couple days but not sure.
