It's a very prudent thing to have a baby. Many people will have a due date when they are pregnant. So what is the probability of birth in due date? What are the signs of birth in due date? Below and four seas net small make up understand next!
What is the probability of birth in the expected period? The probability of birth in the expected period is only about 5%.
The expected date of delivery is the date of delivery. Every pregnant woman has her own due date. Reasonably speaking, the expected delivery time should be an accurate result after detailed clinical calculation. However, it is difficult for every pregnant woman to accurately judge the time of conception. Therefore, according to the medical regulations, the pre delivery period is calculated from the first day of the last menstruation. The total pregnancy period is 280 days, 10 pregnancy months (28 days per pregnancy month). In addition, the birth of the fetus is affected by the factors such as the intrauterine environment, the development of the fetus, the physical conditions of pregnant women and the real environment, so the birth time can not be accurately predicted. Therefore, the due date will become a reference value rather than an exact value. According to scientists, only about 5% of women give birth on the day of expected delivery. The probability of being born within 3 days before and after the due date is 29%, while the probability of being born within 2 weeks before and after the due date is 80%. The probability of being earlier than 38 weeks was 10%, and the probability of being later than 42 weeks (overdue pregnancy) was 10%. Therefore, the probability of birth in the expected period is only about 5%.
Signs of birth in due course
The swollen uterus began to fall, reducing the pressure on the diaphragm. The pregnant women would feel relieved of dyspnea, the pressure of the stomach disappeared, and their appetite increased. The fetus descends, oppresses the bladder and rectum, so that it still feels urine after urination, and does not feel comfortable and happy after defecation. Discharge from cervix and vagina increased.
See red
The discharge of mucinous leucorrhea from the vagina, which contains blood, is known as' seeing red '. Generally within a few hours of seeing red, they should go to the hospital for examination. But sometimes it takes 1-2 days to see the red, and sometimes it takes several days to start the regular uterine contraction. If a large number of bleeding symptoms occur, and the treatment is too slow, it may endanger the life and health of the mother and the fetus; severe abdominal pain, the uterus suddenly stops contracting, and the fetus is still: contact immediately, and rush to hospital for labor.

In case of water break, remember to raise your waist, lie down and rest, head low and hip high, do not stand and walk downstairs, keep quiet, and send to the hospital as soon as possible. The emergency treatment is to put on clean gauze or absorbent cotton first. If there is turbulence after water break, it may cause umbilical cord prolapse. When the fetus has umbilical cord prolapse, it will cause the risk of ischemia or anoxia, especially when the fetus is not in the right position, it can not stand, so we should call an ambulance to send it to the hospital;
Uterine contraction
The vast majority of pregnant women can use the interval of pain as the criterion of admission. When there is pain every 10 minutes, or more than 6 times an hour, pregnant women must first estimate the time they need from home to the hospital, and then call the hospital. The time from the beginning of labor pain to delivery is about half a day or more for the parturient, and half a day or less for the primipara;
Note: it should be noted that from the 28th week of pregnancy, false contractions often appear in the abdomen. If a pregnant woman stands or sits in the same posture for a long time, she will feel the abdomen harden, which is called pseudo uterine contraction, which is characterized by irregular time and weak degree. During the pre delivery period, the condition of pseudocontractions will become more and more frequent due to the stretch stimulation caused by the descent of the lower uterine receptive head.
