Lenght week 39

The future newborn at 39 weeks has already taken the prenatal position. His head is pointing down, he is grouped and tucked his knees to his chin.

The body of the baby fully complies with all the standards that are necessary for a full life outside the mother’s womb. The proportions are observed, and the arms and legs are developed symmetrically. The head is no longer huge, and the bones of the skull are still soft. Passage through the birth canal can begin at any time.

The heart, lungs, intestines, stomach, and other organs have long been ready for complex work outside the uterus. The skin has evened out and the baby already looks healthier and more mature. A little more and the long-awaited meeting will take place.

Detailed moments of the development of the baby:

IntestinesFormed primordial feces – meconium. It consists of dead epithelial cells, and amniotic fluid and has the appearance of a swampy, dense mass. The intestine is completely passable. It gradually moves the meconium into its lower sections.

CNSSucking and swallowing reflexes develop. The salivary glands and the chewing apparatus are not yet developed. The CNS is unevenly developed. Sensitive analyzers, the spinal cord, and part of the facial nerve have matured. All other stages of improving the nervous system will continue after childbirth.

BodyHead of normal size. The shoulder girdle and chest are better developed than the lower body. The reason for this is the peculiarities of blood circulation. The lower limbs are in a greater tone.

PlacentaThe process of aging of the placenta begins. It becomes thinner and changes its structural characteristics. The functioning of this organ is reduced. Some vessels are gradually emptied and cease to perform their tasks. The degree of maturity of the placenta is now above one.

Sense organsEverything is ready to fully perceive the world around us. The baby hears sounds and reacts to them. He recognizes his mother’s voice. Eyes react to bright light. The organs of vision can focus. Developed taste buds.

ScullFontanelles are preserved between the bones of the skull. These are soft areas formed from cartilage. This design makes the bones of the skull malleable for the birth process. It will be easier for the baby to pass through the birth canal.

39 Weeks Pregnant Symptoms

A woman is increasingly faced with the harbingers of childbirth by the 39th week. False contractions may appear, the stomach drops, the mucous plug comes off, and the stool changes.

Does not leave the nesting instinct effect. Women want to transform and improve everything around them. The feeling that by the time the child arrives everything should be as perfect as possible. Sometimes such manifestations go beyond common sense. Mental instability may be observed: arbitrary causeless crying, mood swings, irritability. Anxiety about childbirth intensifies.

Braxton Hicks contractions False contractions at 39 weeks can be confused with prenatal. Remember that Braxton Hicks contractions are short, infrequent, and not intense. They are not accompanied by the discharge of water and the opening of the uterus. There should be no bleeding or severe pain.

False contractions are not the beginning of the delivery process. They only prepare a woman for the upcoming birth. The duration of such fights is not more than 60 seconds. The next contractions will appear no earlier than in a few hours.

Lightning crotch This type of pain occurs suddenly and abruptly. It is localized in the pelvis and vagina. It is fast, sharp, and penetrates the lower body, descending to the legs. The intensity of such sensations is very strong but short-lived.

Such lightning-fast pain can occur with a sharp change in position or careless movement. The main cause of pain is that the child is in a prenatal position. It presses on the birth canal, which causes sharp and rapid pain.

Diarrhea Diarrhea can start as early as the 36th week of pregnancy. The causes of diarrhea can be the natural cleansing of the body, pressure on the intestines, or a change in hormonal levels. Appetite may decrease along with diarrhea. These are directed processes to prepare for childbirth.

Severe diarrhea can cause dehydration. It is worth increasing the amount of drinking when such a symptom occurs. The positive factor of such a symptom is that it will be easier to give birth when the intestines are empty.

Nesting instinct The woman most likely already knows him. This symptom only intensified by the 39th week. There is an acute desire to improve everything around, to transform, to make it more ideal for the appearance of a baby. Sometimes the needs that arise go far beyond the normal. A pregnant woman wants to completely change the wallpaper and furniture or radically redraw the design.

The nesting instinct can be expressed in increased housekeeping, stockpiling, and constant cooking.

Vaginal discharge Mucous discharge is considered normal when it is formed and viscous. Not abundant streaks of blood may appear. This sometimes happens when there is uterine erosion or when a capillary in the vagina bursts.

The following discharges are considered pathological: abundant white, cheesy (a sign of thrush), intensive bloody, brown, bright yellow, and greenish. Do not confuse discharge with amniotic fluid leakage or loose mucous plug.

Pelvic pain The divergence of the pelvic bones can cause severe pain. The ligaments are loosened and preparations are underway for the upcoming birth. The child begins to gradually approach the birth canal, exerting strong head pressure. It evokes a wide variety of sensations. There may be pulling, aching pains, and sensations of strong pressure.

There is no way to relieve such pain because strong painkillers are contraindicated.

All Pregnancy Symptoms     

Childbirth can begin at any time and this greatly increases the level of anxiety of a woman. The expectant mother becomes more fussy, distracted, and preoccupied. She constantly complains about new symptoms and may begin to actively gather in the hospital.

There is emotional instability. A woman can be nervous for no good reason, get annoyed, and change her mood several times a day.

“Be ready to go to the hospital at any time. Keep in touch with your doctor.”
