Fetal movement all over the stomach has no relation to the birth of a boy or a girl and cannot be used to determine the sex of the fetus. Fetal movement occurs around the 20th week of pregnancy, and some women may feel it earlier, as early as the 16th week of pregnancy. When you first feel the fetal movement, it is relatively weak. As the pregnancy progresses, the fetal movement will gradually increase and reach its peak at 32-34 weeks of pregnancy. Fetal movement running all over the stomach may be active fetal movement and is not related to the sex of the fetus. Pregnant women can observe the condition of the fetus in the uterus through fetal movement in the middle and late stages of pregnancy. Fetal movement is generally more regular, if there is a sudden increase or decrease in fetal movement, there may be intrauterine oxygen deprivation of the fetus, and you need to consult a doctor in time for examination. Pregnant women do not need to be too concerned about the gender of the fetus, the health of the fetus is the most important thing.
