The time of labor varies according to the individual’s physical condition and the number of births, generally ranging from 8 to 24 hours. If the contractions occur once every 10 minutes, it means that the labor has already entered into pre-term labor, and the interval between contractions will become shorter as time goes by. For first-time mothers, their adaptation and regulation of labor reaction is poor, so the time between labor initiation and formal delivery will be prolonged, usually with redness and regular uterine contractions for warning, most of them need 8-24 hours, while for menstruating mothers, they may be able to deliver soon, at this time, they need to go to the hospital obstetrics department in time for delivery. This is to ensure the safety of mother and baby. During this period, the mother should monitor the fetal heart rate and fetal movement, pay attention to rest, eat a balanced diet, eat less and eat more, and seek medical attention when abnormalities occur.
