Baby kicks less hard

A

Hi everyone,

I m 20 weeks pregnant with my first one and the last 3 weeks I could feel the baby kicking quite frequently & hard. However the last 3 days I didn t really feel anything. Sometimes I think I feel a small kick however it is just one & really soft. However maybe I m just imagining things & don t actually feel any kicking... anyone else experienced this? Should I be worried?
