Can you use Tylenol a lot?

Is it ok to take a Tylenol whenever you have a headache? I only ever use it when i’m in a lot of Pain. My mom said it was bad if used excessively…
I’ve had a bad headache on and off for 2 days though and i took a Tylenol whenever i felt it coming back… is that wrong?
I feel a lot better now though and the Headache’s gone.
