40 weeks and a miracle

The baby spends about 38 weeks in the womb, but the average length of pregnancy is estimated at 40 weeks. This is because pregnancy is counted from the first day of the last menstrual period, not from the date of conception, which is generally two weeks later.

Your pregnancy doctor can give you an estimated due date for your baby. Your journey as a couple will prove to be a long process of profound change. Here’s what baby will surprise you with from one week to the next!

Week 1

Since the probable date of birth is calculated from the first day of the last menstrual period, this week is counted as 40 weeks, although conception is not yet complete.

Week 2

Towards the end of this week, the egg is fertilised by sermatozoa.

Week 3

Thirty hours after conception, the cell splits in two. Three days later, this cell, also called a zygote , divides into 16 other cells. After another two days, the zygote migrates from the fallopian tubes into the uterus. Seven days after conception, the zygote implants in the uterine lining. At this stage, medically speaking, the zygote is called a blastocyst.

Week 4

At this stage, the baby is smaller than a grain of rice. But cells divide quickly and lay the foundations for systems in the body.

Week 5

At this stage, the central nervous system (brain and spinal cord) is formed.

Week 6

At this stage, the cell formation is called an embryo and measures approximately 3 mm in length.

Week 7

At this stage, the embryo’s heart is beating. The placenta and amniotic sac are developed and provide optimal conditions for feeding and growth.

Week 8

The embryo is now about 1.3 cm long. The head is larger compared to the rest of the body, resulting in a disproportionate appearance.

Week 9

The embryo develops eyes, mouth and tongue. The muscles in training begin to allow him to move more and more often.

Week 10

The embryo has become a foetus and is about 2.5 cm long. All organs of the body are formed. Fingers and toes are starting to appear. The brain is active.

Week 11

The heart is constantly growing. Temporary tooth buds are formed.

Week 12

Fingers and toes are distinguished and defined, although they are still attached to each other with a skin.

Week 13

The foetus swims quite vigorously in the amniotic fluid. At this stage of development, it measures more than 7 cm long.

Week 14

The eyes are fully developed and the eyelids are glued shut. Baby can cry. His vocal cords have developed. At this point, he can be caught sucking his thumb. She’s growing fingernails.

Week 16

The shaft is approximately 14 cm long. His eyelashes and eyebrows grew. Taste buds appear.

Week 18-20

In the foetus hiccups occur.

Week 20

The shaft measures approximately 21 cm long. His ears are fully functional, so he can hear muffled sounds from the outside world. The fingertips have developed fingerprints. The genitals are distinguished and the buds of the permanent teeth are formed.

Week 24

The shaft is about 33 cm long. Both the upper and lower eyelids gain mobility, allowing them to open and close their eyes. The skin is covered with fine hair and protected by a layer of wax (vernix). Vernix helps to expel the foetus. It is also practically his first blanket, his first body milk and the first form of protection in the fight against bacteria. Vernix also protects their hearing, by reducing loud noises and having an antiphonal effect. At this stage, the child begins to practise breathing with the help of the lungs.

Week 28

The baby weighs about 1 kg and measures about 25 cm. The body has harmonised with the size of the head, taking on uniform proportions.

Week 32

Baby spends most of his time sleeping. His movements are stronger and more coordinated. In preparation for childbirth, she may have already changed her position by turning herself upside down.

Week 36

The baby is about 46 cm long. Positioned upside down, it should be ready for the birth. If it is born now, its chances of survival are excellent. Her lungs are developing at a rapid rate at this stage.

Week 40

The baby is approximately 51 cm long and ready to be born. Experts cannot explain exactly what factors contribute to the onset of labour. It is most likely a combination of physical, hormonal and emotional factors relating to the child-mother connection.

The week pregnancy test is an immunological test that detects the presence of the hormone hCG (the hormone secreted by the placenta during the first months of pregnancy) in the urine with an accuracy of over 99%. Specifically, it is specifically designed to indicate the age of pregnancy, as follows: from the first to the second week, from the second to the third week and from the third week upwards.
