40 Weeks Pregnant

The 40th week of pregnancy has come. Childbirth can begin any day. The baby is completely ready for life, regardless of the mother’s body. He gained good body weight and height, and all organs and systems work. There is no doubt that the meeting with the child is already very close.

The mother’s body has gone through all the stages of preparation for childbirth. Childbirth is considered late after the 40th embryonic week and there is an “overcarrying of the fetus.” The placenta is already aging and ceases to perform its functions fully. Soon the intrauterine life of the baby will end and a completely new one will begin.

40 Weeks Baby Development

As long as the baby is inside the mother, he will continue to gain weight and height. Although those parameters that have already been achieved are more than enough for active life outside the womb. There is almost no space inside the mother’s belly. The motor playfulness of the baby is reduced. He pushes with more force but less activity and variety.

It's The Size of Watermelon

The fetus at the 40th week is the size of a large watermelon. The uterus has reached the limit of its growth.

The child can no longer change its position but continues to push off the walls. He rests his hands and feet on his stomach so that it can be seen from the outside.

How Heavy is it? 7.75 Lb or 3.5 Kg

The baby has gained just 6% of extra weight since last week. Now his body weight is 3.5 kg or 7.75 pounds. This is already a very good indicator. The child will be born strong and strong.

Exceeding the norm of weight will be an additional difficulty for the passage of the birth canal.

Your Baby is 20.2 inch or 51 cm

The growth of the baby is now due to the lengthening of the limbs. Body length at 40 weeks from crown to heels is 51 cm or 20.2 inches.

Sometimes this figure can be higher. Growth is determined by genetic information.

Lenght week 40

The fetus is considered full-term by the 40th week. All bodies have been formed and have taken their permanent places. The body’s systems are fully functional. The only exception is the digestive, respiratory and excretory systems. They are mature but still work in prenatal mode.

The baby is now in its prenatal position. It is normally directed head down. A C-section is recommended for any other position. The body of the child is grouped. The legs are pressed to the body with the knees to the chin. This is necessary for further passage through the birth canal.

The fetus outwardly completely repeats all the facial features of a newborn. He is plump, ruddy, and with well-smoothed skin.

Highlights of fetal development at the 40th week:

Skin – The body is no longer covered with lanugo down. The skin is smooth, without wrinkles and folds, and covered with original lubricant. It is a natural shade without a translucent mesh of blood vessels.

GI tractNow the organs of the gastrointestinal tract process the amniotic fluid along with the remnants of the epithelium, hairs, and lubricant. Meconium is formed in the intestine, which moves to the lower sections with the help of muscles. The intestines will be populated with microflora after the birth of the baby.

Hair and nailsGenetics determine whether or not there will be hair on the head at birth. The head will be very hairy if there is such a predisposition. Nails have long crossed the line of fingers and can inadvertently scratch the face or body of a newborn.

Skull bonesThe head is of normal size. The bones of the skull are connected by special cartilaginous formations – fontanelles. They will tighten after the baby is born. The skull retains mobility for the passage of the birth canal thanks to the fontanelles.

AdrenalsThis body will begin its active work at the start of the birth process. Immediately there will be an intensive production of adrenaline and norepinephrine. The action of these hormones will help the newborn to adapt to stress and life outside the mother’s womb.

Respiratory systemThe lungs are covered with surfactant and alveoli are formed. The bronchial tree and trachea are well developed. Everything is ready for future work in an oxygen environment.

40 Weeks Pregnant Symptoms

A woman at 40 weeks pregnant has experienced so many symptoms that it is difficult to surprise her with anything. There are times when symptoms are either mild or absent.

The expectant mother is already noticeably tired of her position at 40 weeks. She wants to give birth as soon as possible. This is due to increased fatigue, a certain clumsiness, and even sometimes helplessness. Emotional instability appears at the end of pregnancy.

Stress Stress in the family may increase before childbirth. The woman begins to panic, fear, and worry. She is afraid of the unknown and the fear of complications during childbirth.

This condition can also be caused by hormonal problems. Women are most worried when they realize that they are already overbearing the baby. It seems to them that this greatly harms the child and that something is not going the way it should be.

Braxton Hicks contractions False contractions may appear as early as the 30th week. Some women do not experience this symptom at all. Braxton Hicks contractions at 40 weeks can be confused with precursor contractions. You need to know the clear differences between these manifestations.

Preparatory contractions will not be constant, short, and less painful. They are not accompanied by the discharge of amniotic fluid and the expansion of the cervix.

Fatigue Passed the 9th month of pregnancy. The woman is already a little tired of her position. A big belly is tiring, which significantly limits motor capabilities. It is hard to breathe, walk, sit and even lie down.

Fatigue is also increased due to the energy costs of the body of the expectant mother. There is increased drowsiness, weakness, and fatigue from the slightest movement.

Leg cramps Strong muscle contractions are observed mainly in the evening or at night. They are expressed in twitching, spasms, and pain in the legs. It is difficult to stop such a phenomenon. Seizures are of short duration.

The reason for the appearance of seizures is considered a significant lack of such minerals: calcium, potassium, iron, and magnesium. Similar symptoms occur with a lack of B vitamins.

Pelvic pain Pain in the pelvic region occurs when the bones separate. This happens before childbirth. The nature of the pain can be both lightning-fast and pulling.

The pressure of the fetus on the pelvis provokes the appearance of sharp pains. The divergence of the pelvic bones will cause rather aching, pulling, and longer pains. The beginning of the advancement of the fetus into the birth canal is accompanied by sharp and rapid pain.

Nesting instinct This is a very annoying and not the rarest symptom in the last weeks of pregnancy. It is expressed in increased thriftiness, the desire to redo everything, improve and bring it to the ideal. The woman believes that everything should shine, lie on the shelves, and be in its place by the time the child arrives at home.

Sometimes the nesting syndrome goes beyond the limits of adequacy. It is worth holding back a woman’s impulses to change everything.

All Pregnancy Symptoms     

Any physiological manifestations at the 40th week no longer matter for the expectant mother. She wants to give birth as soon as possible. A woman does not pay attention to many symptoms at all.

Other possible symptoms may include nausea, diarrhea, abdominal itching, and back pain. A pregnant woman is ready to endure everything just to give birth as soon as possible.

“Be patient until the baby is in a hurry to leave your belly. It is believed that it is the fetus that gives signals to the mother’s body for the onset of childbirth.”

All medical examinations are already carried out in the maternity hospital during planned hospitalization. Ultrasound at this time can only be prescribed if there are sufficient grounds for that. The reason for an additional examination may be a multiple pregnancy, cord entanglement, or suspicion of other problems.

Sizes of long bones

Femur 70–80 mm

Humerus 62–72 mm

Forearm bones 54–62 mm

The lower leg bones 61–71 mm

Control of the placenta

Structural formations in the placenta are considered, and their weight and thickness are determined. At 40 weeks the degree of maturity is above one.

Definition of ossification nuclei

The structure of the bones is being studied. Beklar kernels are considered.

3D Image

Many signs of fetal maturity can be monitored with 3D ultrasound. For example, accounting for the echogenicity of the lungs, and liver tissues, and the presence of suspensions in the amniotic fluid.

The diagnostic value and increased accuracy of 3D ultrasound greatly expand the possibilities of examination.

You can take a photo and record a video of your baby using 3D ultrasound. It can be saved to any medium. This will be a great start to keeping an archive of your child’s videos and photos.

Your Body

All the external changes of a woman have already reached their limit. Weight gain will continue until the very birth. The rate of weight gain is significantly reduced with frequent indigestion and reduced appetite.

Women on average gain 10-15 kg by this date. There are times when the weight gain is about 20 kg. This is largely determined by the lifestyle of the pregnant woman and the restrictive diet. The spine is very difficult now. It is better to try wearing a special corset that supports the stomach with severe back pain.

The posture and gait of a woman change a lot. All movements become more measured and smooth. Clumsiness and low mobility appear. Legs often swell. The chest increases in size. Hips expand. Hair and nails grow quickly.

Belly size & Health Conditions

The abdomen at 40 weeks may be abnormal in multiple pregnancies. Few doctors will delay gestation until such a time. A large belly can also be with a normal pregnancy. The circumference of the abdomen can reach up to 100 cm with initially standard initial data. Everything will depend on the overall weight gain and figure of the woman.

Your belly will most likely drop. This is observed immediately before childbirth during secondary pregnancy. This will slightly change the shape of the abdomen and its density.

The state of health of a woman before childbirth should be normal. It is better to limit attendance at events, as immunity decreases. This increases the risk of contracting infectious and viral diseases. General health is normal. There is severe fatigue and pelvic pain may occur.

40 Weeks is How Many Months?

Now already the 10th month of pregnancy according to embryonic terms. 40 weeks have passed since the probable conception and the baby has long been ready to be born. Applications of obstetric terms are more common. It is believed that it is almost impossible to determine the exact date of fertilization of the egg.

It’s been 42 weeks since the first day of your last period. If the birth starts now, then it will still be classified as urgent (started on time). Childbirth is considered late after the 42nd obstetric week.

Future Mom Tips and Highlights

The nervous system of a pregnant woman may fail at 40 weeks. Many women believe that they are already overbearing the baby. They are ready to do everything to see their child as soon as possible. The emotional state of the expectant mother becomes unstable. She panics, gets nervous, and gets stressed out.

Key tips for pregnant women at 40 weeks:

Keep calmYou are now within the limits of labor that will happen at term. There is nothing to worry about even if there is a slight overwearing. This is not a serious problem.

Consider stimulation and anesthesiaYou must decide for yourself whether you will resort to such procedures. Sometimes the choice will have to be made on an emergency basis. It is better to decide in advance how you will act.

Visit a gynecologistTry not to miss visits to the doctor if you do not notice any harbingers of childbirth. The prenatal condition is under control. The doctor can make decisions about your hospitalization at any moment.

Have unprotected sexUnprotected sex stimulates the dilatation of the cervix. Making love helps start the birth process. Try this common method if you want to give birth as soon as possible.

Stay in touch with your birth partnerIf this is a husband, then fill it with all the necessary information. Show videos of joint childbirth, and teach methods of helping with contractions, and massage tactics. Keep in constant contact with your partner and prepare for a trip to the hospital at any time of the day if this is not your husband.

Try not to overeatChildbirth can happen at any time and your stomach should be as clean as possible. The same goes for the intestines. Regardless of which method you chose C-section or natural childbirth.
