At what week of pregnancy do fetal movements start to decrease?

Patient's question:

No

Doctor's answer:

18—20 weeks, conscious fetal movement begins to appear, reaching its peak between weeks 28—32, and gradually decreasing from weeks 37—38. The pregnant woman counts fetal movements three times a day—morning, noon, and evening—while lying in bed, for one hour each time. The total is multiplied by 4 to equal the count for 12 hours of fetal movement.
