Pregnant women in the first 3 weeks will not notice any changes in the body, even without signs of delay. However, women can also start using pregnancy test sticks at home to soon know the results during pregnancy week 3.
1. Changes of the body during pregnancy week 3
1.1. Ovulation – fertilized eggs
Once eggs and sperm have been successfully fertilized, they officially erm together to give a common cell – called a spores. However, with its microscopic size, which is only equivalent to the head of a needle, the prince at this time is not the same as the fetus or the child. This is just a set of about 100 cells, which are growing and growing rapidly. In particular, the outer layer of cells will become placenta, while the inner layer is the embryo later.
Chroma from parents are combining to determine the sex, hair and color of the fetal eye, even forming part of the innate personality. The ovulation will move from the ovulation tube towards the uterus, stay there and continue to divide by anthmandularly throughout the next 9 months. It is these original cells that will create all the parts and parts of a complete baby.
1.2. Lu imperial body and pregnancy hormones
Although almost the first 3 weeks of pregnancy did not have any changes on the outside, inside their body there were active activities in preparation for the formation and development of the upcoming fetus.
The royal family – a structure consisting of many yellow cells, which forms in the follicles after the eggs have fallen. The crown begins to produce the hormones progesterone and estrogen with enough content to nourish the rye for about the next 10 weeks, until the placenta appears and replaces the above task.
About a week after fertilization, the embryo will transplant itself into the lining of the uterus, and the placenta begins to form. Within the next 6-12 days (about the 4th week of pregnancy), the cells of the placenta gradually grow and begin to produce Human Chorionic Gonadotropin (hCG) – a hormone secreted from the human placenta. HCG will continuously increase in the first 3 months of pregnancy, then gradually decrease in the second trimepcle. This is seen as a signal that the ovaries stop producing more eggs, instead activating the production of even more progesterone and estrogen to keep the lining of the uterus from peeling off, as well as contributing to the development of the placenta.
All pregnancy hormones not only play an important role throughout pregnancy, but also cause a series of changes both inside and outside the pregnant woman's body, such as symptoms of sickness. HCG can be found in urine and blood, which is why women will have a home pregnancy test with urine and get a blood test on their first pregnancy visit. However, some first-week pregnant women may not receive a positive result during the pregnancy test and need to wait another 1-2 weeks.
2. Manifestations of pregnant women in the first 3 weeks
2.1. Keen sense of smell
Suddenly feeling extremely sensitive to scents can be a sign during pregnancy week 3. A sharper sense of smell is the very obvious effect of the hormone estrogen during pregnancy, every scent that is hovering in the air around the first 3 weeks of pregnancy, whether very small, or fragrant or unpleasant, is unusually exaggerated. The woman's nose will now smell of the food being cooked at the house next door, the smell of garbage on the corner or the fragrance of the person who has just entered the door.
In fact, this change is not positive because it will aggravate the symptoms of sickness. Therefore, pregnant women in the first 3 weeks should note:
- Stay away from kitchen areas or street eateries;
- When cooking should prioritize microwave use because they tend to cause less odor;
- Open the windows in the house so that the air is ventilated;
- Wash clothes more often, avoid leaving more dirty items in the basket;
- Look for odorless or pleasantly scented soaps.
Women who are 3 weeks pregnant 3 weeks later if they are seriously ill should frankly ask family members to clean up personal items after cooking or exercising indoors, choose a fragrance that smells light and pleasant, as well as brush their teeth after heavy-smelling foods.
2.2. Lower abdominal tension
Symptoms of abdominal tension, or even mild cramps, but not accompanied by bleeding are usually very common, especially during the first pregnancy. Pregnant women in the first 3 weeks do not need to worry too much because this can be a sign that everything is going normally. This feeling is most likely due to the effects of:
- The process of implanting the embryo into the uterus;
- Increased blood flow and thickening of the lining of the uterus;
- The uterus is growing larger;
- Sometimes it's just a symptom of bloating abdominal pain.
Although the body is actively catching up with all the changes that occur inside, the first 3-week pregnant woman can seek the opinion of a doctor during the next pregnancy visits if she regularly feels prolonged abdominal pain.
2.3. Taste changes
The taste buds of women who are 3 weeks pregnant can make most of the food they enjoy smell similar to metal coins. This is because the taste buds in the tongue are heavily affected by certain pregnancy hormones throughout the first trimep. To alleviate this symptom, pregnant women in the first 3 weeks can be accompanied by a main meal with some acidic foods such as:
- Lemon juice;
- Fruit juices;
- Candy has a sour taste;
- Dishes prepared with vinegar.
In addition, cleaning your tongue every time you brush your teeth or rinse your mouth with a little saline are also useful suggestions that you can apply.
3. Tips for pregnancy week 3
- Combination of iron and vitamin C
Combining iron-rich foods with foods high in vitamin C will help increase the absorption of iron – a nutrient necessary for pregnant women to support increased blood volume. If taking cereals for breakfast, pregnant women weeks 3 should be accompanied by a number of berries, including: blueberries, strawberries, mulberry and welfare. In addition, pregnant women in the first 3 weeks can find vitamin C in fruits and vegetables such as kiwi, mango, strawberry, melon, bell pepper, tomatoes and asparagus. Meanwhile, iron is high in soybeans, beef, poultry and dried fruits.
- Choose foods rich in calcium
Calcium is not only good for the mother, but also helps the fetus to build and develop a strong skeleton. This is also a essential nutrient for cardiovascular health, nervous system as well as muscles. If the woman does not replenish the necessary amount of calcium during pregnancy, the body will automatically remove calcium from the mother's bones to transmit it to the baby. Pregnant women in the first 3 weeks 1 day should consume about 1,000 milligrams of calcium-rich foods during the day, equivalent to 4 servings of Greek yogurt, calcium-boosting juices, cereals and sterilized cheese daily.
- High protein supplements
Consuming three servings of protein a day will have the effect of promoting the development of new tissues for the fetus. Each meal should be given protein from skinless chicken or lean beef, with a mass of about 100g, which is equivalent to the size of a western set of cards. Other food sources that are also abundant in protein include: eggs, fish, milk and legumes.
- Pregnancy test at home
Today, home pregnancy test instruments give almost instant results with high accuracy, equally reliable blood tests performed at medical facilities. However, it may take at least 1 week after menstruation delay for the body to produce enough hCG hormones and show up in the results of pregnancy tests. Therefore, if the pregnancy test is negative, the first 3 weeks pregnant woman can check again after a few days. Do not forget to read the instructions for use carefully and make sure to keep all personal tools clean to ensure maximum accuracy.
