You may still not realize it, but your egg cell has been fertilized and you are now officially pregnant this week! You are in the 3rd week of your meaningful journey that will last 40 weeks. These 7 days are very important for you and your baby. Although there are no visible changes in your body, let’s take a look at what you will experience during the 3-week pregnancy, when your baby will take important steps.
Your Baby at Week 3
It should be noted beforehand that the 3-week-old baby is not yet generous in development. In the last days of last week, the egg cell began to fertilize. In other words, the foundation of everything you will experience in the 3rd week of pregnancy was laid last week. This week, the puzzle pieces will come together and complete the fertilization of the egg and form the zygote. Let me elaborate on the process a little more if you wish.
Journey of the Zygote in Week 3
The zygote, which is formed as a result of fertilization and consists of a single cell, undergoes mitotic divisions and begins to become a ball of cells called the blastocyst. The blastocyst moves from the oviduct to the uterus this week and continues to divide as it progresses.
Along with this journey, the baby, which is a ball of cells, reaches the uterus and succeeds in holding on to the uterine wall. With this development, the baby has found the appropriate place to grow and develop. Where the blastocyst attaches this week is exactly the safe area where the baby will grow and develop until birth.
Your baby, that is, for now, a tiny clump of cells, begins to grow and develop rapidly after holding onto the uterus. It increases the level of the pregnancy hormone, namely HCG hormone (Human Chorionic Gonadotropin), which shows its presence little by little last week.
This hormone will allow you to prove that you are pregnant. Because the HCG hormone, the amount of which increases in the blood, is the main ingredient that will cause the pregnancy test to be “positive”. Of course, the hero of the event is not only this hormone. Estrogen and progesterone hormones will accompany the hCG hormone and they will operate in the continuation of pregnancy.
One of the most important developments for 3 weeks of pregnancy is the accumulation of amniotic fluid in the cavity that will form the amniotic sac. This fluid will increase its amount over time and will create a safe environment for the baby to survive until birth.
3 Weeks of Pregnancy Development of Systems of the Baby
Your doctor will refer to the ball of cells that divides rapidly and settles in the uterus as an embryo. There is no organ or system development in this process. It is now a small collection of several hundred cells attached to your uterus that will continue to evolve over the next period.
How Big Has My Baby got?
When it comes to pregnancy, expectant mothers immediately want to see that miraculous creature on ultrasound. 3 weeks pregnant sounds like an abstract concept to parents. Yes, there are some blood values, but these are medical data. However, expectant mothers and fathers want to see their offspring, even though ultrasound, and to be concretely convinced that they are expecting a baby. Of course, this week is too early to take a baby picture.
Values such as the weight and height of the 3-week-old baby, which is still a pile of cells, cannot be mentioned. It doesn’t even look like a bean with the classic embryo image yet. We can say that the blastocyst that attaches to your uterus and opens its place this week is just the tip of a needle. The outer cells will develop into the placenta next week, which provides your baby with nutrition and other functions. The inner cells will form the fetus, the baby.
Mother in the 3rd Week of Pregnancy
Fertilization steps that started in the 1st and 2nd weeks have been signed this week. So fertilization has taken place! Of course, with the effect of this, changing hormone values will initiate many new actions in the body of the expectant mother, and these actions will bring along some symptoms.
If you do not have a planned pregnancy and do not go to regular doctor checks, you probably do not know about your HCG hormone and therefore you are pregnant. Because you haven’t even experienced menstrual delay yet.
But even if you don’t realize it, your body gives pregnancy signals more clearly than in the first two weeks. For this reason, you can experience the pregnancy symptoms that you do not feel in the 1st and 2nd weeks more concretely this week.
Because the 3rd week is much more active in terms of hormonal compared to the previous weeks. In other words, we can say that the effect of hormones is more clear this week. Here are the 3rd-week pregnancy symptoms:
- Mild Bleeding and Abdominal Pain: Implantation bleeding can occur when the fertilized egg passes through the uterine layer with high blood circulation. Bleeding or mild abdominal pain may be due to thickening or even enlargement of the uterus. So far everything is normal. However, if your abdominal pain is in the form of long-lasting cramps or your bleeding is long, you should definitely consult your doctor. Don’t think about the possibility of miscarriage right away, but you need to take the job seriously. Bleeding and abdominal pain can also be caused by a different problem.
- High Sense of Smell: You may react more than usual to an odor that does not attract the attention of everyone. Sensitivity in the sense of smell during pregnancy is caused by the estrogen hormone, which is progressing at a much higher level this week. Sensitivity in the sense of smell can also cause morning sickness. This tenderness will not stay with the 3rd week, it will probably continue for a few more weeks. In case of sensitivity to smell, try to avoid heavy perfumes, spicy foods, and scented cosmetics.
- Metallic Taste in the Mouth: You can feel the change in taste sensations, known medically as dysgeus, until the 2nd trimester, but we can say that the onset of this feeling dates back to the 3rd week of pregnancy. It is possible that the metallic taste sensation in the mouth will continue to increase in the following weeks.
The reason for this is the effect of the estrogen hormone, which causes odor sensitivity. The sense of taste works together with the sense of smell. Therefore, changing estrogen levels during pregnancy can also show wide fluctuations in taste buds. As your pregnancy progresses, the metallic taste will decrease over time as the rate of hormone change slows.
- Nausea: Depending on beta HCG and estrogen hormones, you may experience nausea or even vomiting, especially in the morning. This feeling, which occurred last week, shows itself more clearly among the 3rd-week pregnancy symptoms. The effect, intensity, and frequency of this symptom vary from mother to mother, but you better be prepared for these waves of nausea in the first 3 months.
- Tenderness and Fullness in Breasts: You may encounter a symptom of tenderness in the breasts experienced before the menstrual period last week. But now breast tenderness may be accompanied by fullness.
- Tiredness: The increase in progesterone hormone every day is effective in the formation process of your baby. Of course, the events taking place in your womb will return to you as fatigue. If you experience a feeling of tiredness that never goes away with the symptoms we mentioned, you may gradually suspect pregnancy.
Which Pregnancy Test Gives Positive Results at Week 3?
In the 3rd week of pregnancy, the HCG hormone rises to a certain level. Expected Beta HCG values should be in the range of 0-5 mIU/ml or / 5 -50 / 9 – 130. This hormone plays its peak until the last weeks.
This hormone, which laid its foundation last week and rises this week, is very important for the detection of pregnancy in women. Because both urine and blood tests will decide whether you are pregnant by looking at the density of this hormone. Home pregnancy tests are also sensitive to HCG.
The increase in the hCG hormone first shows itself in the blood. This rise can only show itself in the urine in the following weeks. For this reason, a blood test is preferred instead of a urine test to detect early pregnancy without even experiencing a menstrual delay. Home or clinical urine tests should be preferred after the delay of the menstrual date.
Things to Consider in the 3rd Week of Pregnancy
If you are experiencing pregnancy symptoms and suspect that you are pregnant, you should definitely consult your doctor for a test. The blood test gives you precise results. This period is early for the urine test you do at home.
If you know or suspect that you are pregnant, it would be good to be informed about what you should pay attention to.
- Quit smoking and alcohol use.
- Do not use any medicine on your own initiative, other than those recommended by your doctor.
- Pay attention to your sleep pattern.
- Start the exercises small. (Avoid sudden movements and lifting weights during exercise.)
- Avoid stress as much as possible.
- Start making efforts to improve yourself about pregnancy and baby care now.
In fact, most of the items you need to pay attention to for 3 weeks of pregnancy are important for all pregnancy periods. When you gain sensitivity in the first weeks about the points you need to pay attention to, you can make the situation a habit and pass the process in the best way. That’s what we call keeping it tight!
Nutritional Recommendations for the 3rd Week of Pregnancy
Nutrition during pregnancy is an issue that will be important throughout the process. However, these days when the baby says “hello” to the place where the baby is fully attached to the uterus and will gradually complete its development, you should also pay attention to your nutrition. At 3 weeks pregnant, your body needs more of some vitamins and minerals that you will get through food.
Because the body is completely focused on the 9-month pregnancy process these days. If you are pregnant or think you are pregnant, you should apply some nutritional recommendations that will make it easier for you to contribute to your body and your baby’s development from this period.
- Don’t be late for Folic Acid Support: The first thing that women who want to have a baby should pay attention to in this process is enough folic acid. Because getting enough folic acid during pregnancy is very important for baby development. You should definitely start this support early.
Folic acid greatly prevents the occurrence of neural tube defect (NTD), which can occur in the first weeks of pregnancy.
The primitive nervous system that is first formed in the embryo is called the neural tube. Thanks to the neural tube, the spinal cord and brain can continue to develop. In the case of NTD, the baby may have an abnormal brain and spinal cord development. Although this is not a common situation, experts recommend taking folic acid supplements from the first weeks of pregnancy. Because while this support prevents NTD, it also facilitates a healthy reproductive balance.
Folic acid supplementation, which is important during the first 12 weeks of pregnancy, can be taken through food. However, in order not to leave anything to chance, your doctor may recommend extra supplements to you. Your specialist should determine the dose of this supplement.
Foods containing folic acid; legumes, citrus fruits, green leafy vegetables, nuts, broccoli, Brussels cabbage, avocado, banana.
- Increase Iron and Vitamin C Intake: You will receive advice on getting enough iron and vitamin C throughout pregnancy. You should definitely heed this advice while you’re at the beginning of the road. Vitamin C during pregnancy can help increase your body’s absorption of iron. Vitamin C will also support your immunity by helping to support your increased blood volume. A body with strong immunity and an ideal iron ratio are the desired features for pregnancy.
C vitamin; It is found in fruits and vegetables such as oranges, kiwis, mangoes, strawberries, melons, peppers, tomatoes, asparagus. Iron support; You can get it from soy products, red meat, white meat, and dried fruits.
- Choose Calcium-Rich Foods: Calcium helps the developing baby build strong and healthy bones. Also calcium; is also necessary for heart, nerve, and muscle health. If you do not get enough of this nutritional value during pregnancy, the baby will get the calcium it needs from your bones! For this reason, never skip the detail of calcium support for both your own health and the health of your baby.
Your egg has just been fertilized and your baby is now a ball of cells. So your baby has not started any bone, muscle, and nerve development. However, you should take precautions for these developments that will take place in a few weeks. It is very easy to get the calcium support you need through food. Cheese, yogurt, soy products, broccoli, cabbage, okra, lentil beans, etc. You must add these foods to your daily diet.
- Get Protein: We said that as of the 3rd week of pregnancy, nutrition is very important. The essential point here is plenty of protein support. To give the baby healthy tissues, you should consume two to three servings of protein a day. Among the rich protein sources, the first foods that come to mind are Red meat, white meat, eggs, fish, dairy products, and legumes.
- Drink Plenty of Water: Experts underline that even under normal conditions, approximately 2 and a half liters of water should be consumed per day. However, this routine amount is expected to increase during pregnancy. Due to the physiological state of the mother, the need for fluid gradually increases. Water is also important for future fetal growth. Making your investment now will contribute to the development of your baby and a healthy pregnancy process.
Again, it is recommended to consume plenty of water for nausea, contractions or digestive problems that you will experience in the later stages of pregnancy.
What is Trimester?
If you know that you are pregnant now, if you have not yet reached this information, you will hear the word trimester a lot in the future. We can say that this expression, which we almost never use in daily life, is the only word of the pregnancy process.
This expression, which means “three months” in Latin, is the name given to each trimester of the 9-month gestation period. 3 weeks of pregnancy is covered by the 1st trimester and this period lasts until the 12th week (first 3 months). The 1st trimester is a very important and exciting time period in which the baby takes the steps of formation and development.
During the 3-week gestation period when the egg is fertilized and you are now officially pregnant, you should not neglect your own health while watching your baby’s development step by step. Your baby’s developmental success is directly proportional to your health.
Being aware of this, you should review your daily diet, routines, and habits. Don’t forget that the precautions you take at the beginning of the first trimester will make the progress easier and enjoy the first steps in this exciting adventure.
