How much amniotic fluid is normal for five and a half months

The amniotic fluid index of a five and a half month old baby is between 80 and 180, and the depth of the amniotic fluid can reach about 30 mm to 70 mm. Generally speaking, as long as it is within this range, it is a relatively normal phenomenon. In the middle of pregnancy, the pregnant woman's appetite will be better. At this time, prenatal examinations should be done to monitor some specific conditions of the fetus in the abdomen, so as to ensure the good development of the fetus.

How much amniotic fluid is normal for five and a half months

The normal amniotic fluid index should be within the range of 80-180MM, or the amniotic fluid depth should be within the range of 30-70MM. As long as it does not exceed or is less than this range, it is considered a normal amount of amniotic fluid. Pay attention to B-ultrasound examination to understand whether the amount of amniotic fluid is normal, as well as the maturity of the fetal heart rate and placenta.

Five months of pregnancy fetal development

During this stage, the fetus grows rapidly and changes significantly. At the 16th week of pregnancy, the skin of the fetus is rosy and transparent, and subcutaneous blood vessels can be seen; the boy or girl can be distinguished based on the external genitalia (with the help of ultrasound); the respiratory muscles begin to move; after one month, the skin gradually turns dark red and becomes opaque, and fetal hair, eyebrows, and nails begin to grow. The subcutaneous fat of the fetus during this period makes the skin appear thin; the head is relatively large, with a circumference of about 17.6 cm, the size of an egg, and about 1/3 of the body length; the bones and muscles are stronger than before, and the limbs are more mobile, so the mother can feel the fetal movement.

During this period, the normal fetal heartbeat gradually becomes stronger, with a fetal heart rate of 120 to 160 beats per minute. After 18 weeks, the fetal heartbeat can be heard through the mother's abdominal wall with a stethoscope. At the same time, the fetus can also hear stronger external sounds, so prenatal education can be carried out. During this period, the normal fetus is about 18-27 cm long and weighs about 250-300 grams. At this time, the fetus already has the ability to swallow and urinate.

Five months pregnant mother symptoms

1. Pregnant mothers gain at least 2 kg in weight, and some may gain up to 5 kg.

2. This month, the uterus slowly enlarges in the abdominal cavity, and the symptoms of irritation to the bladder are alleviated, so the frequent urination phenomenon basically disappears.

3. At this time, the thickness of the uterine fundus can be measured at approximately 15-18 cm above the upper edge of the pubic symphysis. At 19 weeks of pregnancy, the fundus of the uterus will rise 1 cm per week.

4. The breasts swell more significantly than before, and some pregnant mothers can squeeze out a transparent, sticky liquid that is watery and slightly white. The buttocks also appear rounder due to the increase of fat, and the appearance begins to appear fuller than before.

5. The early pregnancy reaction disappears naturally, and the pregnant mother feels much better physically and mentally.
