In the 40 cycles of pregnancy, 18 weeks of pregnancy is generally the mid stage of pregnancy (4 months plus two weeks of pregnancy, also the early stage of 5 months of pregnancy). It can be clearly seen from the B-ultrasound image that the fetus is frequently moving, with a body length of nearly 14 centimeters and a weight of about 200 grams. So where is the fetal movement at 18 weeks?
At 16 to 20 weeks of pregnancy, it is just when fetal movement can be felt. Although the amount of fetal movement at this stage is not particularly large and the amplitude of movements is also very small, the feeling that the mother can feel at this time is like a small fish swimming, similar to the feeling of bloating or gastrointestinal peristalsis. But an inexperienced mother may not be able to distinguish. At this time, the fetal movement is closer to the navel.
If it cannot be felt, then in a quiet state, there may be some movement on the mother's belly, and the first fetal movement is not very obvious like nerve jumping, which is the signal emitted by the fetus.
Normal fetal movement occurs during two very active peak periods in a day, one from 18:00 to 20:00 and the other from 23:00 to midnight the next day, with the latest being 1:00. The frequency of fetal activity during other time periods is very low, especially in the morning. So, mothers can use the method of measuring fetal movement for one hour each in the morning, noon, and evening to fully grasp the activity status of their unborn baby, and make daily observation records as a reference for obstetricians. If it is not possible to test three times a day, it is also necessary to test once. The specific time can be chosen before going to bed at night, and the most important thing is to have a fixed measurement time every day.
This is the best opportunity for mothers and babies to communicate. Babies are conscious in the womb, and as long as they talk to them, they will respond accordingly. If it's a girl, her basic reproductive organs have developed well; If it's a boy, the baby's genitals can already be seen.
