Baby count kicks ?

Hii, so this is my first pregnancy and i am 25 weeks and 5 days today. I was just wondering do you have to count baby kicks ? Like I’ve started worrying because my baby doesn’t move as often.. like this morning I’ve felt his little kicks but during the day I feel like I’m just to occupied to notice if he kicks and when I do sit down and feel my tummy to see if I can feel him he isn’t kicking and it makes me worry with the you have to count your kicks and if they don’t kick 5 times in an hour or 10 times in 2 hour then to call your doctor. I just need a little reassuring because these pass couple days my baby has been moving but I feel like it’s not a lot.
