Fetal movement at 17 weeks is a normal physiological phenomenon and generally does not cause stomach discomfort Fetal movement is caused by the activity of the fetus, most pregnant women will feel the movement of the fetus at about 20 weeks of pregnancy, but some pregnant women may also feel the movement of the fetus at about 17 weeks of pregnancy, which is a normal phenomenon. Due to the increased sensitivity of the uterus after pregnancy, irregular and painless uterine contractions may occur when the fetus is moving, which are not uncomfortable and do not require special treatment. Fetal movement counting should be performed after 28 weeks of gestation as prescribed by the doctor to self-assess the intrauterine status of the fetus. Normal fetal movement is ≥10 times/2 hours, but when there is a decrease in fetal movement or a gradual decrease or even disappearance of frequent fetal movement, it is necessary to go to the hospital in time, and ultrasonography, fetal heart rate monitoring, etc. to assess the intrauterine condition of the fetus, and timely termination of pregnancy if necessary.
