Pregnancy will change your life forever. It will be different, for the better, they all guarantee. Know the changes that will happen during pregnancy by quarter.
PREGNANCY PER TRIMESTER: FIRST TRIMESTER
Because most pregnant women do not know how to specify the date they had sex, pregnancy begins to count from the last day of menstruation. So in the first two weeks, you are not pregnant.
Each ovary cycle corresponds to ovulation. An egg only lives between 12 to 24 hours. Few sperm can reach the fallopian tubes and only one can pierce the egg. It’s good to see that the window to get pregnant is too short.
The day after fertilization, the egg and sperm fuse and each parent contributes 23 pairs of chromosomes that will give rise to a single cell, the zygote. From now on, the cells begin to multiply at a good pace. After 40 hours, it has 4 cells, the third day has 16 cells and so on. On the fourth day, with 32 cells, the egg ends the trip through the trunk and reaches the uterus and between the fifth and the sixth day, it is implanted in the uterus.
GROWTH OF THE EMBRYO
By the fourth week, the embryo is already well implemented in the uterus, in the form of a disc of about 0.4mm and begins the formation of the neural tube, which will soon form the brain and the embryo’s spine.
The first quarter is a period of great development. Up to ten weeks there is an embryo. It is during this period that all organs and systems are formed. From then on the organs only have to mature. So on the ultrasound of the twelve weeks, you will see fingers, eyes or stomach. The heart is already formed, it pumps blood to the body and you can already clearly hear the beating heart.
By the twelfth week, the eyes are visible, the ears are almost at the definitive site, the genitals already allow to distinguish sex, the respiratory system is formed as well as the entire intra-abdominal gut.
By the thirteenth week, the vital organs – the kidneys, liver, intestines and brain are fully formed. The lungs too but their functions still need to mature. Just as the feet, hands, joints, muscles, limbs, bones, eyes and nose are formed. The first twenty teeth begin to form. Although the ears are not yet fully developed, you can already hear sounds and vibrations.
At the end of the first trimester of pregnancy, the baby measures 73 mm , already yawning and urinating.
PREGNANCY PER TRIMESTER: SECOND TRIMESTER
This is the best phase of pregnancy, the true state of grace! Sleep disappears, no longer sick or vomits, still moves easily, has not yet reached sciatica or things like hemorrhoids. Best of all: start feeling your baby growing at a fast rate.
It’s time to enjoy dating and shopping for the child that’s coming. Do not leave the latter because it may be more physically limited.
The organs continue their maturation process, the marrow is able to form blood cells, the spine is ossified and the baby is able to swallow. The brain starts to grow rapidly. Appears hair, nails, intestines begin to produce meconium (fecal matter). Already he moves and puts his hands to his mouth, swallows and spits the amniotic fluid, the definitive teeth are already in the gums.
All the organs already work in full, except the lungs. The skin is less transparent, already the eyebrows and eyelashes are recognized, it already sleeps and wakes up, not necessarily in the same rhythm of the mother. The baby already has fingerprints, already recognizes the internal sounds of the mother, such as heartbeat and voice.
At twenty-four weeks, your baby is about 32 cm and 600 g , it is already considered viable outside the womb, although it is still a very complicated situation that involves being assisted in the intensive care unit.
PREGNANCY PER TRIMESTER: THIRD TRIMESTER
You’ve reached the last stage! It will gain more volume, your breast can grow a little longer and is preparing for breastfeeding. One day you may notice spots on the brassiere, do not be alarmed, it is a sign that you are already producing colostrum (but it can also happen only after delivery).
Now your baby starts gaining enough weight, in recent weeks can increase 200 g may week. When you gain weight, your hair becomes less wrinkled, more pink and soft. The weight increases more than the length, the middle phalanges of the fingers ossify. He already has hiccups, distinguishes the sweet from the acid and opens and closes his eyes depending on whether he sleeps or is awake.
The brain continues to develop, the neural connections clear and already controls the temperature and the breathing. The organs continue to grow and the head is becoming more proportional to the rest of the body. The sobs begin!
The baby begins to run out of space and folds the legs, which increases the pressure in the pelvic area of the mother. It is possible that you change your position by turning upside down.
The iris is colored but the definitive color will only appear between 6 and 9 months of age, with exposure to natural light. The baby is sensitive to light and already distinguishes it through the uterine wall.
After birth, the baby’s immune system continues to develop so some bones will unite. To facilitate passage through the birth canal, the skull is not yet fully solid. You can leave with the elongated head that, after giving birth, returns to the natural form. The lungs are fully developed.
From the age of thirty-seven weeks, she is considered a full-term baby and can be born at any time. At forty weeks, the baby measures about 50 cm and 3250 g .
