When should I start to see small baby bump? Week 7 now.

I'm in week7 day2, my embriyo is 0.92cm (measured 2 days ago). Am wondering when can I start to see mini baby bump? At least prolly I'll feel safe, I'll know the embriyo is growing. I envy some mummies that they have baby bumps early. I read online that underweight/smaller size mummies will see visible bump earlier? Is't true? I havent been able to exercise due to my ovarian cysts operation in late Jan22. Was only discharged in mid Mar22. My tummy muscles are basically non existence (I ate and sleep whole day for the whole 1 month hosp leave). Since so, will my tummy show faster? 😔 I'm 1.63m, 45kg. But my belly still doesn't show any bump. I'm worried. 😣 #1stimemom #advicepls #firstbaby #pregnancy
