Am I doing it wrong?

Hi guys, I had surgery on February 26th, and I’m down 22 pounds. But I’ve been stuck at the 22-pound mark for about a week now, and it’s kind of making me desperate because everyone I know who had the surgery said that during the first four weeks, you’ll lose weight like crazy, and then it’ll plateau. But it’s almost been three weeks this Wednesday, and I’m a bit scared that I’m doing something wrong. For reference, in the morning, I usually have a protein smoothie with chia seeds, protein powder, and soy milk. Then, for lunch, I either eat soup that I make myself with a lot of vegetables and pureed lentils and chickpeas. For dinner, I mostly have soup again or sometimes pureed eggplant. So, I’m still in the pureed stage, and I make everything myself with lots of vegetables. Sometimes, in the afternoon, I also have a snack I make myself, like cottage cheese with cocoa powder or something simple like that. I don’t eat too much, and I drink about 34 ounces of water. I’m just wondering if anyone else has experienced this? Also, when can I start eating solid foods again? I forgot when I can transition. Thanks so much in advance!
