Do we need to be concerned about amount of baby movements at 20W?

For below 27 weeks as long as got movement in a day should be fine. Need to start monitoring and counting during 28 weeks. And yes during 20w baby dont move at regular timing cause they still small and not so active. My baby sometimes move in the morning then suddenly quiete for few hrs. But once you hit 26w baby will be active and kicking harder

20w is still very early to feel consistent movements, that usually comes in third tri.
