9 months of pregnancy: symptoms and development of the baby

Baby Development

At this stage of pregnancy, the baby will most likely be fully engaged in the pelvis, with the head over the cervix. This is known as cephalic position. If you do not get this position in the next few weeks, your doctor may recommend scheduling a cesarean because vaginal birth could be complicated if the baby is not in the right position.

Although each baby develops at its own pace, on average, a 36-week fetus can measure almost 50 cm and weigh between 2200 and 2800 g, as it is capable of gaining up to 30 g per day.

Development of the fetus in the ninth month of pregnancy

The physical characteristics that the fetus presents in this month of its development are very similar to the ones that will have at birth, because there are only a few weeks left to do so.

The lanugo has almost completely detached from the baby's skin. This, along with the accumulation of fat beneath it, which is already smooth and rosacea, make it look completely human.

If you want to know what the fetal lanugo is and what function it has in pregnancy, we recommend that you follow this link: What is the lanugo?

Almost all fetal organs work to perfection. For example:

The lungs are already fully developed and are apt for the fetus to breathe out of the mother's body thanks to the corticosteroids secreted by the adrenal glands. The digestive system is able to digest the amniotic fluid and its intestines are filled with meconium. meconium is a green, viscous substance that builds up in the colon of the fetus during gestation. It is the first fecal matter that will expel the newborn.

The maternal organism begins to transmit temporary immunity to the fetus through the umbilical cord. This will provide protection against many childhood diseases.

Medical visits and advice

If the ultrasound of the third trimester has not been performed before this month, the logical thing is that it takes place over the course of these weeks. This image test is usually done vaginally and the information you provide is as follows:

Fetal viability is essential to detect and monitor the frequency and heart rate of the fetus to rule out any type of complication.Position of the baby at this stage of pregnancy, it is normal that the baby has already acquired the cephalic position. Checking the position of the baby is very important in planning the delivery.Maturity stage of the placenta

a placenta too old can cause problems of oxygenation and feeding to the fetus. Returns of the umbilical cord

the existence of curls of the umbilical cord, especially around the neck, should be evaluated. If so, it will be necessary to be a little more alert in the course of dilation. It is important to know that it is a very frequent event and it is not a big complication, as long as it is controlled and managed with professionalism.Quantity of amniotic fluidThe volume of this substance decreases as the baby grows. However, a significant decrease in the amount of this fluid may be indicative of a problem of growth or premature labor. Therefore, it is important to control it. Length of the neck of the uterus to control the measurement of the cervix is ??very important in the last weeks of gestation, as it begins to shorten as the time of delivery approaches. Its measurement is used to predict how close the birth is.

In the 9th month of pregnancy, check-ups usually become more frequent, especially in recent weeks. Again, the gynecologist can demand a blood and urine test, as well as measure the weight and size of the pregnant woman.

Strep test

One of the most important tests carried out between week 35 and 37 is the culture for the detection of infections caused by group B streptococcus. This bacteria, which usually colonizes the intestinal tract of adults without causing problems, can reach the vagina and cause serious infections in the baby during birth.

Therefore, many doctors advise routinely perform a vaginal and anal culture to rule out the presence of this bacterium in the pregnant.

The main aspects that can increase the risk of suffering from this pathology are:

  • Have had previous streptococcal B infections during the same pregnancy.
  • A condition of urinary tract infections during pregnancy.
  • Have had a baby with a previous infection by this same bacteria.

In case the culture of the samples taken is positive, it will be necessary to administer antibiotic treatment before the birth to prevent the baby from being infected.

The ninth month a week

The changes that can be noticed in these 4 weeks are very important, since any symptom other than normal can be a sign of childbirth. Here are the main events that can happen during this month:

Week 33

During this week, it is likely that the baby will fit into the pelvis. In this position the baby's anatomy is easily distinguishable.

The placement of the feet below the sternum makes kicks, although they are less energetic due to lack of space, are more annoying when they hit the ribs.

It has been discovered that as of this week, the baby enters the MOR phase (rapid eye movements).

According to experts, ocular activity (MOR) may signal that the baby dreams, which is very important for brain stimulation and development.

Week 34

This week, the baby can measure 46 cm in length and weigh more than 2 kilos. The bones of his skeleton are practically hardened, except for those of the head. The fact that the bones of the skull are softer and have not yet been fitted facilitates the passage of the baby through the birth canal.

On the other hand, the vernix, a greasy substance that covers the skin of the baby, is becoming more dense. This also makes it easier for the baby to go through the vagina in the event of a vaginal delivery.

If the birth occurred this week, it would be necessary for the baby to spend a few days in intensive care. However, you would have high chances of surviving without any long-term health problems.

Week 35

In this week of pregnancy, the bone marrow of the fetus can begin to make its own blood cells during the process known as hematopoiesis.

The fetus reaches its maximum degree of development. He is already a complete human being and dedicates himself exclusively to gain weight, since he is able to acquire between 250-350 ga the week. This will make backaches worse as these weeks pass.

Week 36

Childbirth is getting closer. In fact, it would not be unusual for it to be produced during these days. Therefore, it is logical that the gynecologist recommends to monitor the baby's heartbeat and the contractions of the mother is formed weekly.

Third Trimester Ecgorafia

During this week it is advisable to clarify any type of doubt about the birth, especially in regards to how to act and to whom to call in case of rupture of the bag.

User questions

I have 9 months of pregnancy and I have a lot of flow, is it bad?

During the last weeks of pregnancy it is normal for the flow to increase slightly due to the pressure exerted by the fetus on the vaginal tract. However, if the expelled flow is very consistent and abundant it may be the mucous plug, in which case it is necessary to consult the doctor.

If at 9 months of pregnancy the baby is not positioned upside down, is a cesarean delivery always performed?

Usually, by the 9th month of pregnancy, the baby should be wedged over the mother's pelvis. If your position is not correct, perhaps the best thing to do is schedule a C-section before the bag breaks and labor contractions begin.

Is it normal for the baby to not move in the 9th month?

The movements of the baby tend to decrease as the pregnancy progresses due to lack of space. However, if the fetal activity is completely reduced it is advisable to consult the doctor.
