Is This Just Normal Procedure Or Should I Be Worried ?

This Is My First Pregnancy & I tend to over think a lot of things, I can't help it I want my baby girl healthy but today my Dr told me to track her movements & she had to move 10 times or more every 2 hours .

He said If she moves less to go into the ER , is this something every Dr tells expectant mothers around 34 weeks ? Am I just thinking to much into your opinions would definitely help me 🙊
