Am I worrying too much about my facial expressions looking awkward after getting Botox?

I got Botox for the first time.
After a few days, I can feel that the movement in my forehead has decreased compared to before.

It's fine if you just stay still.
I keep looking in the mirror because it’s not the expression I’m used to seeing when I smile or raise my eyebrows.

I wonder if it becomes natural over time.
Or I'm not sure if the capacity or location was wrong from the start.

In this case, would it be okay to wait a little longer?
I'm worried I might need to contact the hospital again.
