Softer baby movements in 33rd week of pregnancy

Hi Mummies, I am currently 33 weeks 5 days pregnant and today I am suddenly experiencing softer movements of the baby as compared to before Is this normal ? I have heard that as the baby grows the strengths of movements get a bit slow. I can still feel the movements but they are a bit soft. Should I be worried? Looking for advise please #firstbaby #pleasehelp
