How much amniotic fluid grows in a month can not be generalized, affected by the period of pregnancy, individual differences and other factors, generally 15-28 weeks, an increase of 50mL per week, to 34 weeks of amniotic fluid peak. Amniotic fluid is the liquid inside the amniotic cavity, the baby survives inside the amniotic fluid, and the amount of amniotic fluid will have an impact on the healthy development of the baby. Amniotic fluid gradually increases as the pregnancy progresses. The amount of amniotic fluid is synchronized with the growth of pregnancy weeks, but individual differences are large, before 8 weeks of pregnancy only 5~10mL, 8 weeks of pregnancy about 50mL; 11-15 weeks of pregnancy weekly growth of 25mL on average; 15-28 weeks, every week, then increased 50mL, to 34 weeks of amniotic fluid the highest peak, about 984mL; and then gradually decrease, to 42 weeks of amniotic fluid sharp decline. When pregnant, you should follow the doctor’s instructions for labor and delivery, and when the amount of amniotic fluid is abnormal, consult the doctor in time and take care of it under the doctor’s guidance.
