19 weeks pregnant and didn't feel baby kicks

When I was 16 weeks , felt my first baby kick and it used to kick almost everyday till 19week. After 19th week, I don't feel any kicks. I read in articles that baby will be moving near to belly button during 19-20 weeks. I am super bubbly. Don't I feel kicks because of heavy tummy around waist? But whenever I talk to baby, I can feel my heart beat increases around my tummy. Does the baby react to it? #pleasehelp #1stimemom #firstbaby #Babykicks
