Labor does not happen suddenly, but before labor starts, there are often some signs that indicate that the pregnant woman will soon go into labor, reminding every mother-to-be that labor is about to start, called aura of labor. Signs 1: False labor 2 to 3 weeks before labor starts, the mother will have irregular stomach tightness and pain, this is the uterine contractions. This kind of contraction is generally short in duration and not constant, with long and irregular intervals, and the intensity of contraction does not increase, or there may be regular contraction, but there is no progress, not getting denser, and the intensity does not increase, and the contraction will stop after the mother walks or rests for a while, sometimes even after changing the position. Most of the contractions appear at night and disappear in the morning. They cause only slight distension and pain in the lower abdomen or slight lumbago, the cervical canal is not shortened and the opening of the uterus is not dilated, and the key distinguishing point is that there is no blood discharge from the vagina. It is not necessary to go to hospital. If there are 1 or 2 contractions within 10 minutes, the intensity of which is enough to cause abdominal pain or lumbago, and each contraction lasts for half a minute or more, the development trend is that the intensity gradually increases, the duration gradually lengthens, the interval gradually shortens, and the frequent and strong uterine contractions make the pregnant woman unable to sleep, this kind of regular uterine contractions is a sign of the beginning of labor, usually called labor, commonly known as “labor pains”. At this time, you should prepare for hospitalization, regardless of whether you have seen red or broken water. Signs 2: Fetal descent feeling pregnant women feel more comfortable in the upper abdomen than before, the feeling of pressure disappears, the amount of eating increases, and breathing is easy, which is due to the fetal previa entering the entrance of the pelvis and making the bottom of the uterus fall. This is due to the fact that the fetal previa enters the entrance of the pelvis and makes the bottom of the uterus drop. The redness is a reliable sign that labor is about to start, as the fetal membranes near the endocervix are separated from the uterine wall and the capillaries rupture with a small amount of bleeding, mixed with the mucus in the cervical canal and discharged through the vagina, which is usually dark red or coffee-colored. However, the actual situation is that many people give birth only a few days or even a week after seeing red, so when redness appears, if there are no regular uterine contractions, the mother-to-be and her family should not be nervous and panic, but stay home for observation, make mental, physical and material preparations, and do not rush to the hospital, just pay attention to keeping the vulva clean. Wait for regular and gradually increasing uterine contractions before going to the hospital. If you have fresh blood or bleeding that exceeds the amount of previous menstruation, it is not redness but prenatal bleeding disorders such as placenta praevia and placenta abruptio, you should go to the obstetrics and gynecology hospital without delay to prevent any untoward situation. The fourth sign: early water breakage is a large amount of fluid flowing out of the vagina, which cannot be controlled, or a small amount of continuous water flowing, which may be a rupture of fetal membranes. Under normal circumstances, the water breaks before and after the opening of the uterus, but only a few pregnant women break their membranes before delivery, called premature rupture of fetal membranes, commonly known as “early water break”. Some pregnant women will go into labor soon after the rupture of membranes, while others will wait for some time before going into labor. Premature rupture of the water is a common abnormality in late pregnancy, which is more harmful to the pregnant woman and the fetus. After rupture of membranes, the uterine cavity is open to the outside world, which increases the chance of upstream infection; it also increases the risk of cord prolapse when the fetal head is not yet fixed or the fetal position is not correct, especially in breech and transverse positions. Therefore, regardless of the presence of uterine contractions, the mother should be sent to the hospital immediately in a lying position, never in an upright position or sitting up, so as to avoid the umbilical cord prolapse, resulting in serious consequences. Those with confirmed ruptured membranes should be admitted to the hospital. To prevent the occurrence of infection, local sterile perineal pads should be used. There are many causes of premature water breakage, usually related to vaginal infection. Other causes include excessive amniotic fluid, abnormal fetal position, relaxation of the internal cervical os, multiple pregnancies, and some nutrient deficiencies (vitamin C, copper and zinc) leading to fetal membrane dysplasia. However, most mothers-to-be with premature water breakage have no way to find out the cause. How to prevent the occurrence of premature water breakage? 1. Go to the hospital regularly for prenatal checkups. Generally, when you are 5-7 months pregnant, check once a month, when you are 7-9 months pregnant, check once every half month, and when you are 9 months pregnant or more, check once a week. If you find excessive amniotic fluid or abnormal fetal position, correct it. If the endocervix is loose, make an endocervical ring ligation at 14-16 weeks of pregnancy; 2. The physiological characteristics of pregnancy can easily lead to mycosis fungoides and other gynecological inflammatory diseases. Therefore, pay attention to pregnancy hygiene, pay attention to maintaining a balanced diet, ensure adequate intake of vitamin C, vitamin D, calcium, zinc, copper and other nutrients, and maintain the toughness of the fetal membranes. 3.If there is more discharge and infection during pregnancy, you should go to the hospital and receive treatment in time; 4.It is not advisable to have intercourse in the second trimester (the last month); 5.In case of multiple births, you should rest more in bed; 6.Avoid overexertion and punching to the abdomen.
