3-4 weeks of pregnancy: ultrasound, hCG, signs
Nature is so laid that the birth of a child is the main goal for a female representative. The time when the lady is preparing to become a mother, is the most welcome and beautiful in her life. During the period of gestation, the female body undergoes tremendous changes. They occur outside and inside the body of a future mother.
Every girl and woman should know what can happen in her body at the time of 3-4 weeks of embryo development. The signs of developing pregnancy can be different. As well as the results of ultrasound and a blood test on the definition of hCG.
How does conception occur?
For starters, it's worth mentioning how fertilization takes place. Throughout the month, the female body undergoes cyclical changes. This is due to the development of certain hormones at the right time.
Approximately in the middle of the menstrual cycle, ovulation occurs. At this point, the egg leaves its place of growth and enters the fallopian tube. This is where the meeting with the main childbearing cell of the male body occurs. After the fusion of the cells, continuous division begins and promotes them to the uterus. It is there that the embryo will develop all the next months.
Methods of counting the weeks of pregnancy
There are two ways to calculate the duration of pregnancy: obstetric and fetal. The first one starts from the moment when the last menstruation came. The second begins when the fertilization of the female cell with the sperm has occurred. It is worth noting that it is the embryonic period that is more accurate. However, it can not always be precisely established. That is why almost all specialists prefer to use the midwife's method of calculating the weeks of pregnancy.
Early development of the embryo
3-4 weeks of pregnancy are considered the early period of embryo development. The period with this name will last about 10 weeks. It is from this moment on that the embryo becomes an embryo and assumes human outlines.
Term 3-4 weeks of gestation: a description
During this period, a woman may not yet be aware of her interesting situation and not notice the changes in her body. But by this time within the body of the future mother there are already complex processes, and hormonal restructuring is taking place.
The kid at the 3-4 weeks gestation period does not yet look like a human. However, the cells of his body continuously divide, and the body increases with every second. During this period, the most important organs and systems are being formed. In the fetal egg, three layers are formed, from which a skeleton, blood and nervous system, as well as all organs, will form in the near future.
Concentration of hCG during this period
At 3-4 weeks of pregnancy, a human chorionic gonadotropin is formed in the woman's blood. It is this substance that is always produced when the ovum is fertilized.
It should be noted that all home pregnancy tests work on the principle of determining this hormone. A reagent is applied to the strip, which detects HCG upon contact with the test material. If the test sensitivity is too low, the result may be negative. Do not get frustrated ahead of time. If you can not wait to find out if conception has taken 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 the blood test. In the urine, the amount of chorionic gonadotropin is somewhat lower.
So, if your pregnancy period is 3-4 weeks, but you are not sure of your situation, take a blood test and everything will clear up. 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 during this period for ultrasound. It is worth noting that not always a doctor can please you with a good result. Implantation of the fetal egg in the wall of the genital organ can occur from 3 to 10 days after fertilization. The earlier this action takes place, the faster it will be possible to detect pregnancy on the screen of an ultrasound machine.
The examination in this period is carried out using a vaginal sensor. The doctor applies a special gel on it, which allows you to make contact and see the image of the female's internal organs.
During this period, the doctor marks the condition of the endometrium. Measurement of the genital organ in three planes is also carried out. In addition, the doctor examines the appendages. In the normal state by this time in one of the ovaries should be a yellow body, which was formed after ovulation.
If you already see a fetal egg, then it is measured. Also, the doctor examines his cavity and notes the presence or absence of the yolk sac, which will subsequently become the embryo and embryo.
Mistaken ultrasound at 3-4 weeks
In some cases, a frozen pregnancy is diagnosed on ultrasound (3-4 weeks). Such an verdict can be borne by 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 his heartbeat. The only thing that can result from this examination is the identification of the fetal egg. The diagnosis of "undeveloped pregnancy" can be mistaken for lack of an embryo. Do not immediately run on scraping. Wait another two weeks, and, perhaps, by that time, an embryo will appear in the fetal egg.
Signs at 3-4 weeks
Most often in this period, a woman does not feel absolutely nothing. But if the pregnancy is desired and the future mother listens attentively to herself, she can note some changes in her body and state of health. If the period that your pregnancy has is 3-4 weeks, the symptoms may be different. Consider the most common of them.
Nausea and vomiting
The most frequent symptom of the onset of conception is an early toxicosis. It is worth noting that some women manage to avoid it altogether. Also, nausea may appear at a later date.
If you have a pregnancy 3-4 weeks, signs of an early toxicosis can be expressed in the following. You get up in bed in the morning and feel a slight nausea. After eating, an unpleasant feeling can intensify. Quite often there is vomiting, which does not bring relief.
In addition, the expectant mother reacts strongly to those smells that she did not notice before. Often pregnant people feel sick of the flavor of fried or boiled meat.
Dizziness and weakness
At this time, the future mother may face a decrease in blood pressure. This is quite normal phenomenon, which does not threaten the woman and her future baby. It is worth noting that hypertension is very dangerous in this situation. That is why nature has made it so that in future mothers blood pressure becomes somewhat lower.
At sharp movements the woman can feel an easy or a light; a mild dizziness. Also, the future mother constantly wants to lie down. It becomes difficult for her to get up early in the morning.
Increased vaginal discharge
Another symptom that can say that you have a pregnancy 3-4 weeks is allocation. At this time, the nature of the mucus and its quantity vary greatly. Allocations become more, they are similar to a thick cream with trailing transparent veins.
Such vaginal mucus is absolutely normal. However, if there is an unusual color of discharge or they have an unpleasant smell, it is necessary to contact the district gynecologist and take the analysis.
If you have a pregnancy 3-4 weeks, the discharge begins to form a stopper, which will protect your baby from bacteria and infection throughout the entire period. All this mucus will be released immediately before the onset of labor.
Condition of the nervous system
Under the influence of produced hormones in a future mother in the early stages of pregnancy (at 3-4 weeks) can greatly change the mood. It would seem that a few minutes ago the woman laughed, but now she is sad or even crying.
All households and relatives can suffer from such sudden changes in mood. It is necessary to have patience and be kinder. This state will not last long. It will be held together with early toxicosis and malaise of a future mother. This occurs on average in 12-14 weeks of pregnancy.
Changes in the body
In addition to all the signs described, a woman can feel that something is going on in her body. Often at this time, future moms notice an increase and engorgement of the mammary glands. Nipples become more sensitive and may darken. This occurs under the influence of progesterone, which is produced in large numbers by the yellow body and adrenal glands.
Also, women feel tingling in the lower abdomen. During the introduction of the fetal egg into the wall of the genital organ, painful sensations can arise. Some representatives of the weaker sex even have a slight implantation bleeding, which can be taken as the beginning of a new cycle. It is worth noting that such allocation ends very quickly. Any prolonged bloodshed is the reason for an urgent appeal to a specialist.
If you have a pregnancy 3-4 weeks, a photo of the fetal egg can be obtained in the office of ultrasound. 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 for the future baby. If you feel unwell, consult a specialist who leads your pregnancy.
