Hi Danii, I'm in Perth Aust. My op was 18/7 so 5 weeks out for me. I've dropped 15kgs so far. I had dropped 15kgs in the first 3 weeks then put on 2kgs. My dr explained that was just the body rehydrating and now I've lost that too. But I noticed that even though the scales haven't been moving much the last couple weeks, my cms have dropped.
So yeah I would say your loss seems great and very on par
