Frequent fetal movements in the morning may be caused by the fetus being more active, but it may also be caused by fetal hypoxia and so on. Generally women will be able to feel the fetal movement around 18 to 20 weeks of pregnancy, and you can usually determine whether the fetus has hypoxia by observing the fetal movement. If there is frequent fetal movement in the morning, it may be a physiological phenomenon, because usually after the pregnant woman gets up in the morning, the fetus will be more active, and the fetal movement will be relatively frequent. And if the pregnant woman is angry or excited, diet, etc., may lead to changes in fetal movement. If you usually get up in the morning after the fetal movement is not frequent, suddenly appeared frequent fetal movement, need to consider whether the fetus has intrauterine hypoxia, to go to the hospital in time to do ultrasound, or to do fetal heart rate monitoring and so on.
