lesser movements?

Hi mummies, these days i notice that my baby doesn't move or kick around as much as the weeks before and not even the time that she is usually active. Not too sure if i have been moving around or didn't take note(notice) hence i couldn't feel her movements but as far as i know i have been bedresting most of the time. I am getting worried, tho she did move at some times of the day i just feel like she's not as active.. is it normal now that i am at 30weeks?
