How long can feel the fetal movement, generally pregnant women in about 20 weeks of pregnancy can feel the fetal movement, but there are individual differences in the specific time, such as pregnant women and abdominal fat layer is relatively thin pregnant women can sense the fetal movement earlier, if pregnant women more than 20 weeks still can not feel the fetal movement, need to be alert to the fetus whether to stop developing. If the pregnant woman is more sensitive, thin abdominal fat, a few in about 16 weeks of pregnancy can feel a slight fetal movement, if the pregnant woman sensitivity is poor, and abdominal fat thick, feel the time of fetal movement may be delayed, but the latest generally will not be more than 20 weeks, so if the pregnant woman 20 weeks of pregnancy is not yet obvious fetal movement, to go to the hospital in time to check the development of the fetus. It is recommended that pregnant women should do Down’s syndrome in time after 13 weeks, and pay attention to the presence of fetal movement between 18 and 20 weeks, after the appearance of fetal movement, go to the hospital in time to check, pay attention to monitor the number and frequency of fetal movement is normal, and do a good job of all the pregnancy checkups.
