No worries, usually it is because the movements are too soft and not appreciable by you.

Just make sure you have regular check ups. At this stage the fetus would be around 500gm, lack of fetal movements doesnt have the same implication as in later stage of pregnancy

However once the fetus grows bigger, when it can survive outside the womb, reduce fetal movements might become an urgent matter as sometning can be done to bring it out.
