Pregnancy Month by Month: The growth of the baby in the uterus causes a series of alterations in the mother’s body.
The development of a baby is a wonderful experience but also involves a series of problems for the mother, so it is advisable to be prepared for the consequences of pregnancy in the body.
In this article, we will detail how pregnancy symptoms progress month by month and how the embryo develops into a baby.
Pregnancy Month by Month (and Week by Week)
Below we describe the most common symptoms of pregnancy for months and weeks, as well as the development of the baby during each period.
1. First month (weeks 1-4)
After a sperm reaches the egg, the embryo descends through the fallopian tube until it reaches the uterus and is implanted in the uterus, usually between the eighth and tenth days. The placenta also develops, through which nutrients are transferred to the baby.
If you are pregnant, you will not notice any symptoms except that you will not lower your period. Some tests can detect pregnancy after the fourth week.
2. Second month (weeks 5-8)
During the second month, you are more likely to begin to notice symptoms such as fatigue, morning sickness, increased need to urinate, hormonal fluctuations and tingling in the nipples. The uterus increases in size and your body may widen a little.
Between the fifth and eighth weeks, the brain, heart and other vital organs of the baby begin to develop. During this period the umbilical cord is formed, which connects the blood of the mother with the placenta.
3. Third month (weeks 9-13)
The embryo is called a fetus in the third month of pregnancy: the main parts of the body of the future baby have already appeared and will continue to develop during the following months. At eight weeks the fetus already has the appearance of a tiny baby. At the end of the third month, the risk of spontaneous abortion is reduced.
In the third month morning sickness decreases but you are more likely to feel burning, indigestion and bloating, as well as having cravings or feeling aversion to some foods. The breasts increase in size during this period.
4. Fourth month (weeks 14-17)
In the fourth month of pregnancy, the baby’s hair has begun to grow, his bones have hardened and it is possible to hear the beating of his heart in the doctor’s office. Sometimes the thumb is even sucked. When the end of the fourth month arrives the sexual organs have been formed so that you can already know the sex of your baby through ultrasound.
We recommend that you begin to sleep reclining on the left side of the body and with pillows on the back and between the legs to facilitate the circulation of blood. You may feel some symptoms of constipation, varicose veins, and nosebleeds. It also usually decreases the need to urinate.
5. Fifth month (weeks 18-22)
The baby will start kicking during the fifth month of pregnancy. They begin to develop their skin and their sense of hearing, while their circulatory and urinary systems are already functioning.
When you reach this period it will probably become evident that you are pregnant. Among the usual symptoms in these weeks are back pain and headache, dizziness, inflammation of feet and ankles, indigestion, burning, constipation, and fluid retention. It also increases the risk of developing urinary tract infections.
6. Sixth month (weeks 23-27)
In the middle of pregnancy, the baby is almost completely formed and its growth rate decreases, but it is accumulating fat to maintain body temperature.
As the baby grows you will also gain weight. Other symptoms of the sixth month include constipation, burning, hemorrhoids, and indigestion.
The baby can already perceive and process rhythms and melodies; If you talk to him, sing to him or make him listen to music, he is likely to relax when he hears the same sounds once he is born. Other people will be able to hear the beat of your heart putting the ear in your belly.
7. Seventh month (weeks 28-31)
When the third trimester of pregnancy arrives, we recommend that you finalize the preparations for the delivery as it approaches more and more. You may begin to feel the contractions of Braxton Hicks, which consist of tension and distention of the uterus as if you were preparing for childbirth.
Again, the frequency with which you need to urinate will increase. You may also feel cramping in your lower back, severe headache, or blurred vision; If these last symptoms happen, you should consult your doctor.
The baby’s brain begins to process images and sounds, and goes through the REM phase while sleeping; This could mean that you start to dream.
8. Eighth month (weeks 32-35)
In the eighth month, the baby’s body has practically finished its intrauterine development. He is gaining weight at a rapid pace, his lungs are almost fully formed and he recognizes sounds and voices. If everything goes well, it will be placed face down, in its final position.
You may start to secrete colostrum, a fluid that precedes breast milk. Braxton Hicks contractions become more likely during the eighth month.
9. Ninth month (weeks 36-40)
During the last month of pregnancy, you will notice more symptoms, such as discomfort, pain, fatigue, Braxton Hicks contractions, the pressure in the pelvis and difficulty falling asleep. The baby’s immune system becomes strong during the last weeks of pregnancy, preparing for the outside world.
Prepare for the possibility of premature birth, since your baby can be born at any time. For the rest, we can only say congratulations!
