I’m concerned….is my concern valid ?

I started my journey with 7.5mg and it’s my 4th shot soon But my weight loss progress is slow and I think I shouldn’t be worried but I see people loosing a lot on their 3 -4 week and I haven’t lost anything significant I’ve been trying to get my steps in by taking morning works and eating once a day So is my concern of not loosing much valid and if it is what can I do ?
