3-4 weeks of pregnancy: ultrasound, hCG, signs
Nature so laid that the birth of a child - the main goal for the female. That time, when the lady is preparing to become a mother, is the most awaited and beautiful in her life. In the period of carrying a baby, the female body undergoes tremendous changes. They occur outside and inside the body of the future mother.
Every girl and woman should know what can happen in her body during the period of 3-4 weeks of embryo development. Signs of developing pregnancy may be different. As well as the results of ultrasound and blood tests for the determination of hCG.
How does conception happen?
First of all, it is worth mentioning how fertilization takes place. Throughout the month, the female body undergoes cyclical changes. This is due to the production of certain hormones at the right times.
Around the middle of the menstrual cycle ovulation occurs. At this point, the egg leaves its growth site and enters the fallopian tube. This is where the meeting takes place with the main reproductive cell of the male body. After the fusion of cells together, continuous division and their advancement to the uterus begins. It is there that the embryo will develop in all subsequent months.
Methods for counting weeks of pregnancy
There are two ways to calculate the duration of pregnancy: obstetric and fetal. The first originates from the moment when the last menstruation occurred. The second one begins when the fertilization of the female cell by the sperm cell occurred. It is worth noting that it is the embryonic period that is more accurate. However, it is not always possible to accurately install it. That is why almost all experts prefer to use the obstetric method of calculating weeks of pregnancy.
Early development of the embryo
3-4 weeks of pregnancy are considered to be the early term of the embryo. The period with this name will last approximately 10 weeks. From that moment on, the embryo becomes an embryo and takes on a human shape.
Term 3-4 weeks of pregnancy: description
During this period, a woman may not yet be aware of her interesting position and not notice changes in her body. But by this time inside the body of the future mother already the most complicated processes are taking place, and hormonal changes are taking place with might and main.
Baby on the term of 3-4 weeks of pregnancy does not yet look like a person. However, the cells of his body are continuously dividing, and the body grows every second. During this period, the most important organs and systems are formed. Three layers are formed in the ovum, of which in the near future a skeleton, the circulatory and nervous systems, and all organs will be formed.
HCG concentration in this period
In the 3-4 weeks of pregnancy in the blood of a woman human chorionic gonadotropin is formed. This substance is always produced during fertilization of the egg.
It is worth noting that all home pregnancy tests work on the principle of determining this hormone. A reagent is applied to the strip, which, upon contact with the material under examination, detects hCG. If the sensitivity of the test is too low, the result may be negative. Do not be upset ahead of time. If you can not wait to find out whether the conception took place, you can donate blood to determine the level of this hormone.
It is worth noting that at this time the level of hCG increases daily. 3-4 weeks of pregnancy are characterized by the amount of substance from 25 to 125 mIU / ml. This number is indicated for blood tests. In the urine, the amount of chorionic gonadotropin is slightly lower.
So, if your gestational age is 3-4 weeks, but you are not sure of your position, take a blood test and everything will become clear. You can get the result within one day, but more often the research is done in a few hours.
Term 3-4 weeks of pregnancy: ultrasound
Many women, in anticipation of conception, run for ultrasound during this period. It is worth noting that the doctor may not always please you with a good result. Implantation of the ovum into the wall of the reproductive organ can occur from 3 to 10 days after fertilization. The sooner this action takes place, the sooner it will be possible to detect pregnancy on the screen of the ultrasound device.
Examination during this period is carried out using a vaginal sensor. The doctor puts on it a special gel that allows you to make contact and see the image of the internal organs of the woman.
During this period, the doctor notes the condition of the endometrium. Also measurement of the reproductive organ in three planes. In addition, the doctor examines the appendages. In normal condition, by this time in one of the ovaries there should be a corpus luteum, which was formed after ovulation.
If the fertilized egg is already visible, it is measured. The doctor also examines its cavity and notes the presence or absence of the yolk sac, which later becomes the embryo and embryo.
Ultrasound error for a period of 3-4 weeks
In some cases, a missed pregnancy is diagnosed on ultrasound (3-4 weeks). Such a verdict can make an inexperienced specialist. It is worth noting that at this time it is still impossible to detect the embryo and even more so to see its heartbeat. The only thing that may be the result of this survey is the identification of the ovum. The diagnosis of "non-developing pregnancy" may be mistaken due to the absence of an embryo. Do not immediately run to scraping. Wait another two weeks, and perhaps by this time the embryo will appear in the fetal egg.
Signs for a period of 3-4 weeks
Most often, during this period, a woman feels absolutely nothing. But if the pregnancy is desired and the future mother attentively listens to herself, then she can note some changes in her body and well-being. If the duration of your pregnancy is 3-4 weeks, the signs may be different. Consider the most common of them.
Nausea and vomiting
The most common symptom of the onset of conception is early toxicosis. It is worth noting that some women manage to avoid it at all. Also, nausea may appear at a later date.
If you have a pregnancy 3-4 weeks, signs of early toxicosis can be expressed as follows. You get out of bed in the morning and feel a little nauseous. After eating, an unpleasant feeling can intensify. Quite often there is vomiting, which does not bring relief.
In addition, the expectant mother strongly reacts to those smells that she had not noticed before. Often pregnant feel sick from the aroma of roasted or boiled meat.
Dizziness and weakness
At this time, the expectant mother may face a decrease in blood pressure. This is quite a normal phenomenon, which does not threaten the woman and her future baby. It is worth noting that hypertension is very dangerous in this position. That is why nature has done so that in future mothers blood pressure becomes slightly lower.
With sudden movements, a woman may feel light-headed. Also, the expectant mother always wants to lie down. It becomes hard for her to get up early in the morning.
Vaginal discharge increase
Another symptom that can say that you have a pregnancy for 3-4 weeks is a discharge. At this time, the nature of the mucus and its quantity vary greatly. Discharge becomes more, they look like a thick cream with stretching transparent streaks.
Such vaginal mucus is absolutely normal. However, if there is an unusual color of discharge or they have an unpleasant odor, you must contact your local gynecologist and pass the analysis.
If you have a pregnancy of 3-4 weeks, the discharge starts to form a cork that will protect your baby from bacteria and infection throughout the entire period. All this mucus will be released immediately before the onset of labor.
State of the nervous system
Under the influence of the hormones produced by the expectant mother in the early stages of pregnancy (3-4 weeks), the mood can vary greatly. It would seem that a few minutes ago a woman was laughing, and now she is sad or even crying.
All households and relatives may suffer from such sudden mood swings. It is worth patience and be kinder. This state will not last long. It will go along with early toxicosis and future mother's ailments. It occurs on average at 12-14 weeks of pregnancy.
Changes in the body
In addition to all the symptoms described, a woman may feel that something is happening in her body. Often in this period, future mothers notice an increase and engorgement of the mammary glands. Nipples become more sensitive and may darken. It occurs under the influence of progesterone, which is produced in large quantities by the corpus luteum and adrenal glands.
Also, women feel tingling in the lower abdomen. During the introduction of the ovum into the wall of the genital organ, painful sensations may occur. Some representatives of the weaker sex even have a slight implant bleeding, which can be taken as the beginning of a new cycle. It is worth noting that such discharge ends very quickly. Any prolonged hemorrhage is the reason for an urgent appeal to a specialist.
If you have a pregnancy of 3-4 weeks, a photo of the ovum can be obtained in the ultrasound room. It shows the clear contours of the bubble, in which the future baby will grow and develop.
Carefully monitor your health during this period. Now you are responsible not only for yourself, but also for the future baby. If you feel unwell, consult a specialist leading your pregnancy.
