| PREGNANCY WEEK BY WEEK |
The development of the baby in the womb begins after fertilization occurs. Self-fertilization generally occurs two weeks after the date of your last menstrual period.
In addition to being part of pregnancy, the date of the last menstrual period (First Day of Last Menstruation) is also used to predict the date of delivery, by adding 40 weeks from that date.
First Trimester
In the 3rd week of pregnancy, the fertilized egg will begin to develop and form a sac that contains the fetus (embryo) and the placenta. Fetal blood cells begin to form and hundreds of other cells develop, and blood circulation begins.
By the end of the 4th week, the fetal heart tube is in place and can beat up to 65 times per minute. By the end of the first month of pregnancy, the fetus is 0.6 cm long, smaller than a grain of rice.
Pregnant women also begin to experience pregnancy symptoms, such as easily tired and enlarged breasts. The increase in the pregnancy hormone HCG also causes menstruation to stop, and this is one of the early signs of pregnancy.
At week 6, a face with large circles for the eyes, nose, mouth, ears and lower jaw and throat has begun to form. The fetus has begun to look curved like the letter C.
By the 7th week, the fetus is starting to form hands and feet, and the uterus has now doubled in size.
By the 8th to 10th week of gestation, the fetus has successfully passed a critical period of organ development and body structure, has measured almost 3 cm in length, is more mobile, and looks more like a human. In this week, the baby in the womb is ready to develop.
Between the 11th and 13th weeks, your baby's brain will develop rapidly, his kidneys will begin to excrete urine and his fingers will be able to clench like fists. Entering the 12th week, the baby's genitals have begun to be formed. The length of the baby in the first trimester will reach 8 cm.
Second Trimester
Entering the second trimester, the risk of miscarriage will usually decrease, because your uterus is getting stronger and continues to grow. The weight of the baby in the womb has reached 42 grams with a length of 9 cm.
His bones and skull hardened and his hearing increased as well. You may feel a kick and a pounding heart, and you may be able to see various expressions on an ultrasound examination.
In the 14th to 15th week, his sense of taste is formed and he has begun to be able to detect light.
In the 16th to 18th week, the baby will experience a growth spurt and his genitals are well formed so that they can be seen during an ultrasound examination.
At the 19th week, the baby in the womb can already hear your voice. Entering the 20th week, the baby will swallow more and produce feces or meconium.
At 21 to 22 weeks, babies are very active and increasingly look like little humans. Babies also have started to grow eyebrows and hair at the age of 25 weeks, and their weight is increasing because they already have fat.
At the 26th week, the baby can start to inhale and expel the placental fluid which is a good sign, because then he is also practicing to breathe.
At week 27, your baby in your womb can open and close his eyes, suck his fingers, and even hiccup. You may feel amused when he does this.
Third Trimester
Entering the third trimester, the baby's weight can reach 1 kg with growing muscles and lungs. His head continues to grow to follow the development of nerve cells in his brain. His wrinkled skin became smoother as his body fat continued to grow.
He can already blink, his eyelashes and nails are growing, and he has more hair. In this final trimester, the baby will gain more weight, so that in total it can reach about 3 kg with a length of 48 cm.
At 31 to 33 weeks, your baby's kicks will be stronger and you may start having false contractions. The growing uterus can cause heartburn and shortness of breath. You will also feel more and more uncomfortable in bed.
At week 34, the central nervous system and lungs will be more mature and movement is not as frequent or intense as before. The baby in the womb will descend further into the pelvic area at 36 weeks as the due date approaches.
At week 37, you will experience more frequent vaginal discharge and contractions. During pregnancy, you are advised to be aware of the symptoms of a condition called preeclampsia, which is a pregnancy complication characterized by increased blood pressure, protein in the urine, and swelling in the legs.
Your water will probably break at 39 weeks. If this happens, it means you are about to enter labor. Immediately contact your doctor, midwife, or hospital where you plan to give birth for help.
Sometimes, there may be pregnant women who have not shown signs of labor even though it has passed the due date. Don't worry if you experience it, because it can happen.
However, if the pregnancy is too old or reaches 42 weeks, you may need to undergo a labor induction procedure.
Discuss with your doctor about a safe and appropriate delivery procedure for your pregnancy. Routinely check the baby in the womb can also help you to anticipate abnormalities or problems that may occur.
