There is a question on Zhihu: Should I give birth to a baby at nine months or ten months of pregnancy? How should I put it? It’s not an exaggeration to say it’s nine months, it’s okay to say it’s ten months. The pregnancy cycle is calculated based on 280 days. If we follow the natural month we usually use, then 280 days is just a few days more than 9 months. Can you say that giving birth in 9 months is wrong? But in fact, in medicine, the gestation month is not calculated as 30 days, but 28 days. So 280 days is 10 gestation months, each gestation month has 4 weeks, and the entire pregnancy cycle is 40 weeks. The time it takes for a fertilized egg to mature is 264 days, which is 38 weeks. Therefore, the fetus is actually full term after 37 weeks. \”Ten months of pregnancy\” is such a smooth saying. Why is it not September? In fact, it is not all because: it is originally ten months of delivery. However, very few babies will actually be born on the day of the 40-week due date. About Only about 5%. Most other babies are born within two weeks before and after the due date, and babies born within this period are full-term babies. Why are some babies born at 38 weeks and some at 42 weeks? The first reason is: Conception time is different. In fact, there are many things that look the same but are different between people. For example, the menstrual cycle is 28 days for some, 25 days for others, and 35 days for others. Different menstruation periods The cycle also determines the different times of ovulation, so the time of conception is also different. Since the times of conception are different, even if the due dates of the fetuses are similar or even the same, the actual birth times are not necessarily the same.

The second reason is that the maturation time of the fetus is different. As mentioned above, it takes 264 days for a fertilized egg to mature. This is normal. But if there are abnormalities, such as chronic intrauterine hypoxia, malnutrition and other reasons that cause slow growth, then it will take more time to wait until the fetus matures to start delivery. Or maybe some fetuses develop better and faster than we expected, and the baby may come out early. Of course, this is at full term. The third reason: The physique of pregnant women affects the time of delivery. Will the physique of pregnant women affect the time of delivery? It may sound a bit unbelievable, but it is true that the physical condition of the pregnant mother also has a certain impact on the time of delivery of the fetus. However, this is a relatively deep subject, and this is the general meaning. I have a friend who gave birth to three babies in total. Each time, the onset of pregnancy occurred just after the 37th week of pregnancy. This happened to all three babies. The doctor clearly told her that she was born prematurely. Fortunately, the baby\’s weight was not the same. It was too light, weighing a little over five pounds, so even if the fetus was not completely full term at the time (a few days away), the baby was no different from a normal full-term fetus. Of course, whether you are giving birth at nine months or ten months, you need to pay great attention to the later period, because some things may not develop as you imagine, so you need to pay more attention to it later. First of all, we must remember to go to prenatal check-up on time. fromAfter 36 weeks of pregnancy, you should have a check-up every week. In addition to the previous routine check-ups, fetal heart rate monitoring will also be added. This item can most directly check whether the fetus is hypoxic. It is very important not to reduce your daily count of fetal movements. Then, pregnant mothers should be prepared to give birth at any time. The fetus is full-term after reaching 37 weeks, and it is possible to give birth at any time. As for the items needed for delivery, it is best for pregnant mothers to prepare in advance so that they can carry their bags and move in at any time. Pay attention to whether you have symptoms of water rupture, redness or uterine contractions. Water rupture and urinary leakage are relatively similar. There are also certain differences between uterine contractions and false uterine contractions. If you really can\’t tell the difference, it\’s best to go to the hospital directly when encountering this situation. , it’s better to get it wrong than miss it. If you see redness, no matter how much it is, you can go to the hospital immediately to wait for delivery. If you have experience, you can wait until the labor pains to go to the hospital when you see a small amount of redness. It is best for pregnant women with special circumstances to be hospitalized in advance to wait for delivery. Finally, if it has not started by the expected date of delivery, the pregnant mother must remember to increase the frequency of prenatal check-ups, and go for a check-up every 2-3 days to ensure that the fetus is still growing in a good uterine environment. At the same time, pregnant mothers should also pay attention to safety and avoid In case of collision, especially protect your stomach. If the baby still doesn\’t start at 41 weeks and insists on staying in the mother\’s belly, then don\’t be so calm at this time and go directly to the hospital. As for what to do, it is best to listen to the doctor\’s arrangements. You should also learn to regulate your emotions in daily life, and don\’t let bad emotions cause trouble to you. The correct answer is to be more happy and joyful. Generally speaking, the saying \”Ten months of pregnancy and one day of delivery\” is not just rhetoric, it is because the fetus is really born after ten months of pregnancy. As for the specific day, it depends on the baby\’s mood.
