To all the excitement associated with the novelty of the first sensations of pregnancy, adds experience and about how not to miss the beginning of labor.After all, everything happens for the first time!As it happens, when you start the first birth, and how they should proceed - all this does not rest nulliparous mums.
unlikely that such fears are not without foundation - genera almost never start suddenly.The first hints of the approach of the long-awaited moment of the birth of the beloved man beginning to be recognized for 2-4 weeks.
During this period, hormonal changes a woman's body.If the entire 9-month period the body of a pregnant woman lived under the influence of the female hormone progesterone, at the end of pregnancy, he gives way to estrogen.
role of progesterone in the period of gestation was the fact that he provided the fetal growth and its successful development.Progesterone provide proper tone of the uterus, the necessary concentration of oxygen and nutrients in the bloo
At some point, the fetus in the womb to mature, to start preparing for the release of "the light."To help him comes another female hormone - estrogen, progesterone replacement, the concentration of which begins to decline.Important role of estrogen in the first and in the second stage of labor.It determines how fast the first stage of labor revealed the cervix, and how much will be flexible and able to stretch the vaginal wall.And this, in turn, determines the duration of attempts.Home delivery is usually determined by two main features: on the scramble for discharge of amniotic fluid.
concentration of estrogen is important in the onset of labor, that is, during labor.The fact that the battle takes place in connection with the emergence of the nerve impulse, which appears after the desired level of hormone concentration.In fact, the complex process of births occur reflexively and further regulated by the nervous and hormonal systems of the female body.Quest, which is a reduction of the wall of the uterus - a reaction to the irritation of its nerve cells that produce at this moment active substances, which in turn are used to prepare the next bout.The process of acquiring the cyclical nature of the fights and continues until the final exit of the fetus outside.The contractions occur at intervals of time between them comes a lull in such moments the uterus relaxes and the woman is not experiencing any sensations.
Influenced fights happening:
- in the 1st stage of labor: the disclosure of the uterine cervix;the duration of the bout 10-15, the intervals between contractions - 15 minutes or more;
- in the 2nd stage of labor: the movement of the baby through the birth canal and its birth;contractions intensified and lengthened intervals between them are reduced;
- in the 3rd stage of labor: the rejection of the placenta from the uterine wall;with parts of the placenta and umbilical cord membranes, ie the birth of the placenta;the duration of the bout 2-3 minutes.
discharge of amniotic fluid
The sac of a pregnant woman usually contains about 800 ml of amniotic fluid, although this figure may reach 1.5-3 ml.Water is clear and odorless, but if they have a greenish hue, this indicates poor condition of the child (fetal hypoxia).Even before the fetal bladder contractions may get a break.With a small gap of water will leak.No pain a woman feels is not.Prior to active labor in reserve mothers have a few more hours.
If you have at least some of the above symptoms should immediately take steps to ensure that further passage of labor took place under the supervision of doctors.
nulliparous mom more than any other fear "skip" the beginning of birth, no time to get to the maternity hospital.It is unlikely that in practice it happens.It should be noted that most often takes for nulliparous women giving birth is not the beginning of his signs, and his precursors.While greater vigilance at first birth is never superfluous.
Approximation of birth can indicate certain signals, which are called forerunners.About them pregnant women learn closer to 36 weeks.Forerunners first 36 weeks suggest that the female body prepares itself for childbirth.They also continue to occur just before the birth.Consider them.
- belly omission .This is due to the displacement of the baby in the lower abdomen, so kaktonus abdominals while decreasing.This woman is experiencing some discomfort due to pressure on the bladder and intestines.But when breathing this displacement fetus easier because of reduced pressure on the diaphragm is less disturbed in the stomach heartburn.Nulliparous observed ptosis stomach for 2-4 weeks before the onset of labor, all other women in childbirth - directly before delivery.
- Expansion pelvis .Sacroiliac joint is stretched under pressure potyazhelevshy baby, accompanied by drawing pains in the lower back.Swimming and special exercises for the hip facilitate the situation.
- change in the child's activity .Kid often become sedentary - it cramped in the uterus, especially with the weight of more than 3 kg.But there may be an alternation and its activity: the more, sometimes less.
- irregular contractions .Starting with the 30 th week, there may be painless and irregular contractions that are easily mistaken for a sign of the onset of labor.This so-called false labor, or Braxton-Higgs.Especially clearly they manifest themselves in the 37-39 week.They are characterized by uneven interval (15 min., 30 min., 20 min., 10 min., Etc.) are not amplified.And, as we already know, the true sign of the beginning of birth is a regular and dynamic development skhvatok.Dlyatsya false contractions no more than 2-3 hours, especially in the last week before delivery, which resembles a sort of training before an important period in the uterus true birth.It happens that false contractions smoothly into the regular labor.
- edema and seizures .They result from the pressure of the fetus on the blood vessels of the pelvis.
- Vaginal discharge (mucous plug) .Before birth vaginal secretions may become more abundant.In order not to confuse them with the Dribble amniotic fluid, use a cotton lining that absorbs water and will release on the fabric.For any suspected leakage of amniotic fluid is an urgent need to consult a doctor for the test, the answer to which will be ready after 15-20 minutes.During pregnancy, the so-called mucus plug closes the output channel of the fetus.Cork can move like 2 weeks before delivery, and 3-4 days before the onset of labor.Therefore, its discharge of - not a reason to seek the hospital.
- Emotional instability, change in appetite and decrease body weight (2 kg), protrusion of the navel - as harbingers of labor.
Before birth the woman does not have to occur all at once precursors.For example, 2-3 trait - a common phenomenon during the upcoming birth.But it also happens that a pregnant woman to become a mother and have not experienced the typical signs of early labor.
