Although there are changes every week, the stages of development of the baby in the womb are generally divided into several trimesters or three-month periods. Come on, recognize the points of development of the fetus and your baby so that it is easier to detect if there are abnormalities or disorders in your pregnancy.
The development of the baby in the womb begins after fertilization occurs. Fertilization itself generally takes place two weeks after the date of your last menstrual period. Yup, menstruation is also part of pregnancy, although you are not certain to get pregnant in these weeks. Your last menstrual date (First Day of Last Menstruation / LMP) will then be used to predict the date of labor, by adding 40 weeks from that date.
Next, these are the growth and development milestones that occur in the third week until the last trimester of your pregnancy.
First Trimester
In the third week, as the fertilized egg develops, an embryo and placental sac form. Blood cells form and hundreds of other cells develop, and blood circulation begins.
At the end of the fourth week, the fetal heart tube is present and can beat 65 times in one minute.
At the end of the first month, the fetus is about 0.6 cm long, smaller than rice grains. You will also begin to experience symptoms of pregnancy, for example fatigue and breast enlargement. Increased levels of the hormone HCG also cause menstruation to stop, and are usually used as a sign of early pregnancy.
By the sixth week, a face with large circles for the eyes, nose, mouth, ears and lower jaw and throat had begun to form. And the fetus has begun to look curved like the letter C.
By the seventh week, the fetus begins to form hands and feet, and the uterus has now doubled in size.
In the eighth to tenth week, the fetus has made it through the critical period of development of its organs and body structure, has been measuring almost 3 cm in length, is moving more and looks more human. This week, the baby in the womb is ready to develop.
In the eleventh week to the thirteenth baby's brain will develop rapidly, his kidneys begin to pass urine and his fingers can clench like fists. The baby's length will reach 8 cm. Entering the twelfth week the baby's genitals have begun to be formed.
Second Trimester
Entering the second trimester, the risk of miscarriage will also decrease because your content is getting stronger and growing. The weight of the baby in the womb reaches 42 grams with a length reaching 9 cm. His bones and skull have become increasingly hardened and his hearing ability has improved. You might feel a kick and see it making various expressions through special ultrasound or ultrasound examinations, for example 3-dimensional ultrasound or 4D ultrasound.
In the fourteenth and fifteenth weeks, his sense of taste was formed and he had begun to detect light. The baby will experience a growth spurt in the sixteenth week and his genitals are well developed, so they can be seen during an ultrasound examination.
In the 19th week, the baby in the womb can already hear your voice. Entering the 20th week, the baby will swallow more and produce a type of fetal feces called Meconium. Babies will increasingly look like little humans at gestational age entering the 22nd week. He can also feel movement and begin to grow hair. The baby will gain weight because he already has fat.
At the 26th week, the baby can begin to inhale and release placental fluid (amniotic water) which is a good sign, because by doing so he is also practicing breathing.
By the 27th week, the baby in your womb has been able to open and close his eyes, suck his fingers, even hiccups. You might feel amused when he does this.
Third Trimester
Entering the third trimester, the baby's weight can reach one kilogram with muscles and lungs that are growing. His head continued to grow to follow the development of nerve cells in his brain. Her wrinkled skin becomes smoother due to the increasing body fat. He can blink, grow eyelashes, nails and more hair. In this final trimester the baby will gain more weight, so as a whole can reach about 3 kg with a length of 48 cm.
By week 31, the baby's kick will feel stronger and you might start having contractions. The growing uterus can cause heartburn and shortness of breath. You will also feel more uncomfortable in bed.
By week 34, the central nervous system and lungs will mature and the movements will not be as frequent or as excited as before.
The baby in the womb will go down more to the pelvic area in the 36th week as the delivery date approaches. You will experience vaginal discharge and contractions more often into the 37th week, and it is advisable to be aware of the symptoms of a condition called preeclampsia (pregnancy complications marked by hypertension and also damage to fetal organs).
Your amniotic fluid may rupture in the 39th week. If this happens, it means you will immediately go through the labor process. Contact your doctor, midwife, or hospital as soon as possible.
Don't worry if you miss the prediction of your delivery date. This is a common thing. However you may have to go through an induction procedure if the gestational age has reached 42 weeks. Discuss with your doctor about childbirth procedures that are safe and in accordance with the conditions of your pregnancy.
