Weekly chart of pregnancy development

Pregnancy is like a "travel". Once you are pregnant, you have embarked on a "travel" journey. After the pregnant woman gives birth to the "angel baby", she has arrived at the end of the travel. In order to make the "travel" happy, you must master the health knowledge during pregnancy and do a good job of self-monitoring, so that the fetus can grow and develop normally. Let’s take a look at the creation process that Dingsheng’s mother has sorted out for everyone:

Week 1

Are you ready? If you and your husband have decided to have a healthy product, then choose to start your healthy stage now! This week you may experience the biggest change in your life. From today you will enter a new stage and you will become a mother. Wish you happiness!

In the second week, your menstrual cycle has entered the second week. The ovulation period is usually on the 13th to 20th day of the menstrual cycle, so on the 2nd Sunday, your ovulation period will begin. Now you should develop a more detailed pregnancy plan, which should include your work schedule, health care, diet and family financial planning.

The third week is now the ovulation period. Has your body temperature changed during the ovulation period? You may be pregnant this week. You should maintain a happy mood during the conception period and try not to have conflicts with your husband. Pregnancy after happy events or compassion will affect the quality of sperm and egg combination. It is easy to get pregnant on the 13th to 20th day of each menstrual cycle. Since the ovulation time is relatively fixed, the quality of sperm is very important. Obstetricians at Assisted Fertility Center said that the lifespan of egg cells in the bilateral fallopian tubes is only 12-36 hours. Sperm can survive for 3-5 days in a good cervical mucus environment, but pregnancy usually only occurs within 24 hours after sexual intercourse.

The fourth week has come. You may not feel anything yet, but the embryo has quietly "implanted" in your uterus! The pregnant mother has not noticed the changes in her body, right? Now your uterine wall is affected by the hormones secreted by the ovaries, becoming thicker, softer and more nutritious, the blood vessels are slightly dilated, the water is abundant, the sperm and egg combine to continue dividing, and after moving into the uterus, a solid cell mass is formed, called a mulberry body. At this time, the sperm and egg combination is called a blastocyst.

Week 5 After entering the 5th week, your "best friend" has not yet visited you. Are you happy or anxious? Some pregnant mothers who are planning to get pregnant may have found abnormalities in their bodies. Now you can go to the hospital for a pregnancy test to find out whether you are pregnant.

Week 6: By week 6, your pregnancy symptoms begin to become apparent. If you haven't taken a pregnancy test yet, now is the time to go to the hospital. Your body has already begun to change and symptoms of pregnancy are appearing. Due to the stimulating effects of female hormones and estrogen, your breasts feel swollen and painful, your breasts become larger and looser, and small nodules appear on your nipples. You will often feel tired, sleepy, and urinate frequently.

Week 7: You are in week 7 of pregnancy. When you wake up in the morning, you may feel indescribable nausea and an indescribable pungent smell in your mouth, sometimes like the smell of gasoline or other chemical materials. This is a situation that most pregnant women encounter in the early stages of pregnancy.

After the eighth week, the fetus has begun to take on human form. Technically, your baby is still an embryo because it still has a tail, which will disappear over the next few weeks. The 9th week of pregnancy is called the fetal period. The embryo's heart and brain are now more complex, with creases beginning to appear on the upper eyelids, a slanted nose, arms becoming more bent at the elbows, and a small bend above the heart.

Week 9: It has been 9 weeks since you were pregnant. Have you adapted to the various symptoms of pregnancy? The morning sickness after waking up in the morning will soon be over. Now do you want to know the changes of the fetus in your belly? The tail of the fetus in the test tube embryo period has disappeared, and all the changes of the fetus have occurred. Look! We have begun to call the test tube embryo "fetus". The present stage is a critical point, that is, a critical period of your entire pregnancy, from which the fetus begins to grow and develop its organ system.

The tenth week of pregnancy has entered the tenth week. Your baby is now very much like a little person. His (her) body length is about 40mm and weighs about 10 grams. Now he (she) has been prepared to grow up, and will grow up quickly in a short time, which will surprise you. Now the basic cell structure of the fetus has been formed, and all parts of the body have become complete, including arms, legs, eyes, sex organs and other organs. However, these organs are still in the development process and have not yet fully grown and matured.

Eleven Weeks of Pregnancy You are now in the eleventh week, and your early pregnancy is about to come to an end. Now the early pregnancy symptoms have begun to ease, and in a few days your nausea, retching and loss of appetite will be over. You will often feel hungry, and eating a lot of food every day cannot meet your needs. Now your fetus is 45-63mm long and weighs 14 grams. The fetus's growth rate is accelerating, and it has begun to suck, swallow, and lift its legs in your womb. His (her) life-sustaining organs have already developed and matured.

The twelve-week-old fetus is now about 65mm long, and the prototype of the human body has already been developed from tooth germs to nails. The baby's fingers and toes have completely separated, and some bones have begun to become hard and form joint prototypes. In the next 6 months, the main task of the fetus is to diligently absorb nutrients from the pregnant mother, and then grow healthily, until it can leave the warm and comfortable womb and go out into the world.

At fourteen weeks, your uterus has grown a lot, but it is still difficult for people around you to tell that you are pregnant. Because the fetus is still small, in fact only 76-100mm, weighing about 28 grams, the fetus's fingers have begun to grow fingerprints that represent his (her) own characteristics. After entering the second trimester of pregnancy, the risk of miscarriage decreases. At this time, the early pregnancy symptoms that many pregnant women cannot bear begin to ease, morning sickness tends to calm down, and gastric juice replaces nausea and vomiting. During this stage, the secretions in the pregnant woman's vagina begin to increase.

At fifteen weeks, the baby's head begins to grow fine hair and eyebrows also grow. Now the fetus has a layer of fine fur on its thin skin, like a fine fur blanket covering him (her). This layer of fur will usually disappear when he (she) is born. Some of the fetus's muscles begin to work. During this week, the fetus can do many postures, such as clenching his hands, squinting his eyes, frowning, making faces, sucking his thumb, etc. These postures can help the fetus develop its brain as soon as possible.

The sixteen-week fetus is now about 12 cm long and weighs 150 grams. It still looks very small and is just the right size to fit in the palm of your hand. Want to know what new changes will happen to the fetus this week? Now he (she) has begun to learn to burp slowly, which is a precursor to breathing, but you can't hear the burp sound. This is because the fetus's bronchi are filled with amniotic fluid instead of air. It's that exciting time in pregnancy when you can feel your baby move.

At 18 weeks, the fetus begins to move regularly. In this week, the fetus's eyes, which were originally biased to the sides, begin to focus forward. The fetus's bones have turned into rubber-like cartilage and are beginning to harden. The fetus is already close to 14 cm long and weighs about 200 grams. Starting from today, within a few weeks you will be able to actually feel the baby's fetal movements, and your stomach will feel floating around. Many pregnant women record the time when they first felt the baby's movements.

The 19-week fetus now weighs about 225 grams and has doubled in size compared to last month. When you do an ultrasound in the second trimester of pregnancy, you can draw a rough outline of the fetus based on the ultrasound. When you do this examination with your husband, he can see the fetus lifting its legs, bending its body, stretching its waist, turning over, and sucking its thumb. Doctors can now clearly identify the sex of the fetus, but because some parents currently have gender discrimination tendencies, doctors generally will not tell you the sex of the fetus.

You must be very happy that you have entered the second trimester of pregnancy healthily at 20 weeks. Now the length of the fetus has reached 16.5 cm and the weight has reached 250 grams. The fetus's visual organs enter a critical period of development, and the brain begins to divide special areas for the development of smell, taste, hearing, vision, and touch. If the baby is a girl, there are probably 6 million eggs in her ovaries now, and the number of eggs will gradually decrease to 1 million when she is born.

21 weeks The fetus is already 21 weeks old, and his (her) weight has continued to increase. This little baby now looks more and more smooth, and his (her) body is covered with a layer of white, smooth substance, which is vernix caseosa. It can protect the fetus's skin from being harmed by long-term immersion in the amniotic fluid of pregnant women. Many babies are born with this milky white vernix still left on their bodies.

At forty weeks a major moment in your life is about to arrive. After ten months of pregnancy and one day of delivery, all the hard waiting will be over, and the long-awaited little life will soon be put into your warm arms. Now doctors can determine the mode of delivery based on the fetus and your physical condition. Most fetuses will be born within this week, but only 5% of babies can be born exactly on the due date. Because a reasonable deviation has been included in the calculation of the due date, it is normal to be born half a month early or late, so there is no need to be overly anxious.
