28 weeks movements

How often should movements be throughout the day?

My baby was super active on first day of 28 weeks, I think I was experiencing braxton hocks at the same time and was a bit uncomfortable.

Second day not so super active movements but still movements. How often should the kicks and movements be strong?

My doctor said baby should move atleast 3 times in an hour and they sleep 1.30-2 hours each time.

Should I be worried and contact my doctor?!

Baby moves but it’s more subtle. This is my first pregnancy past 28 weeks so I don’t know if it’s normal! I do go for checkups every two weeks now.
