4 months pregnant can not feel fetal movement may belong to the normal situation, because each pregnant woman’s specific situation is not the same. The thickness of the abdominal wall is different between primigravid and transient mothers, and the feeling state is different, both will have different feelings, usually primigravid and obese pregnant women, about 4 months pregnant may not feel the fetal movement. Thin abdominal wall or menstruating women may feel fetal movement around 4 months of pregnancy. Not all pregnant women to 4 months will definitely feel fetal movement, if the fetus is relatively small, limbs are relatively weak, the range of the uterine cavity is relatively narrow, resulting in the amplitude of fetal movement is not very obvious, so a considerable number of pregnant women really do not feel fetal movement. At this time there is no need to be nervous and anxious, and do not casually buy a variety of instruments to detect. If you really feel nervous or high-risk pregnant women, you can go directly to the hospital for auscultation, you can get the results, if necessary, the doctor will also provide ultrasound. 16 weeks or so we recommend to come to the hospital to carry out a systematic pregnancy test, the process of pregnancy test there is a very important step, that is, using the Doppler fetal heart rate instrument for auscultation, if at this time to hear the heart of the fetus is very good, you can rest assured. In rare cases, ultrasound may be ordered to predict the risk of preterm labor, miscarriage, or to measure the thickness of the fetal skin.
