23 weeks pregnant baby kicks are less strong??

Om

Hi,

I am 23 weeks 2 days pregnant and my baby’s kicks are less strong than the weeks before. I used to feel his kicks when I lay down on my back or my left side and I would see my belly move up and down. now at 23 weeks pregnant they’re less strong and he doesn’t kick as frequently as before. I am really worried, my OB appointment is tomorrow to check if everything is alright with baby.

Should I be worried?
