Usually in the 5th month of pregnancy, the mother can feel the slight activity of the fetus, and the exact perception of fetal movement varies from person to person. Overall, fetal movement at 5 months of pregnancy is not yet regular and is relatively slight. Depending on the description, it can be like a small fish swimming in the stomach, like a pulse beating on the abdominal wall, like a bird flapping its wings, like a butterfly flapping its wings, and so on. The sensation of fetal movement is mainly caused by the fetus reaching, kicking or impacting the uterine wall inside the uterus. If a 5-month pregnant woman is thin and has a thin abdominal wall, she will feel the fetal movement more obviously and notice it earlier. If the abdominal wall is thicker and the amniotic fluid is more abundant, pregnant women may recognize fetal movement later and feel it less obviously. In addition, the activities of pregnant women, nervousness, excessive fatigue, smoking, etc. will affect fetal activity. Therefore, pregnant women can feel the sensation of fetal movement at the same time, which will be more clearly perceived changes in fetal movement. Fetal movement is an important indicator of prenatal fetal monitoring, the number, speed and strength of fetal movement can indicate whether the fetus is normal or not. If you do not feel any fetal movement in the 5th month of pregnancy, it is recommended that you go to the hospital to have your doctor monitor your fetal heartbeat, determine the cause and deal with it accordingly.
