A little wetness in the panties is not considered water breakage. This should be incontinence caused by frequent urination or relaxation of the urethral sphincter due to the reduced capacity of the bladder in the second trimester. It is also possible that the cervical opening is dilated in late pregnancy and the cervical canal becomes shorter with discharge, which may also lead to wet panties. If the water breaks, there will be a continuous flow of fluid from the vagina, and the amount of flow is relatively large, and there will be fluid flowing all the time when standing or when there is pressure in the abdominal cavity, and only then is it a sign of water breaking. After the water breaks, you should pay attention to bed rest, do not exercise strenuously, and avoid standing for a long time, which can lead to the umbilical cord prolapse affecting the fetus and leading to intrauterine ischemia and hypoxia.
