Carrying multiple fetuses is called a multiple pregnancy. This situation is much more difficult than in the development of one child. You should try to keep the kids. At what time can twins be determined? The answer to this question is presented in the article.

Signs

Usually the symptoms of early pregnancy are the same anyway. But with twins, there may be a noticeable deterioration in the condition and the emergence of new signs. But only a doctor can determine who is developing - a son, a daughter or twins.

Twin pregnancy can be identified by:

• severe toxicosis;
• the presence of bright stripes on the test, as the level of the hCG hormone noticeably increases;
• rapid belly enlargement during twin pregnancy;
• early baby movements;
• fast weight gain, especially in the 1st trimester;
• high appetite;
• Sharp and severe mood swings.

Morethere is a need for the use of exotic fruits and unusual products, because you need more vitamins and minerals. And the body looks for them in food.

Twin Symptoms

Multiple pregnancy can be determined on our own. But it is better to pass or take place US. The procedure will definitely show twins. Examination helps to note such manifestations as an enlarged uterus, which, for example, at 5 weeks can correspond to 9 weeks. You will need to donate blood for the hCG hormone. If a high score is detected, then this will be another sign.

Blood is examined for the level of iron, alpha-fetoprotein. When there are twins in the uterus, the amount of iron is reduced, and the ACE protein is increased. It will be possible to determine the presence of 2 fetuses by listening to 2 heartbeats, as well as by probing 2 heads, but this is possible only at a later date.

An ultrasound scan is required to rule out a medical error. Only this procedure will accurately determine the exact number of fetuses in the uterus. It allows you to determine the period, as well as the presence or absence of pathologies.

When will it be possible to find out for sure?

When can twins be identified? Usually, the number of fetal eggs is detected by ultrasound at 8 weeks. In this case, the doctor will detect several heartbeats. Who is in the womb - twin boys or girls can also be determined by the doctor.

But, according to experts, this result should not be trusted. A follow-up study at week 12 will be required, as the risk of 1 fetal death is very high. According to statistics, only5 women out of 10 both children survive. This is influenced by the physiology or he alth of the body.

Identical twins

How is identical twins determined? Pass required:

• doctor's examination;
• pregnancy test;
• Ultrasound.

Identical twins are noticeable at 12 weeks, not before. After determining this, after 3 weeks, a secondary study should be performed to confirm the viability of the fetuses.

Frequent ultrasound procedures do not harm children, since only modern technologies are used now. They allow you to accurately track the condition of the fetus and their development.

Manifestation of multiple pregnancy

It is not noticeable on ultrasound: twins are located in the womb or twins, but it will be possible to establish their number. It should be borne in mind that a singleton pregnancy is markedly different from a multiple pregnancy, and the second is diagnosed in different ways.

Diagnosis is performed as follows:

1. First, the complaints of the pregnant woman are taken into account. These signs include the presence of delay, nausea, vomiting, malaise, weakness, drowsiness, swelling of the mammary glands.
2. A study of the anamnesis of menstrual function is being performed. The doctor should be told when the periods were, whether the cycle is regular, and how it goes.
3. Required home test results.
4. HCG blood test in progress.
5. Ongoinggynecological examination, which reveals an increase in the volume of the uterus.

An ultrasound of the pelvic organs is also performed. Usually, ultrasound before 11 weeks is prescribed if there were problems of miscarriage, fetal fading, ectopic pregnancy. In other situations, a planned examination of the body is required.

Development

When pregnant with twins, women are included in the high-risk group, so special medical supervision is required. To do this, you need to go to the antenatal clinic: every 14 days until 28 weeks, and then after 7-10 days.

At each examination, the weight of the pregnant woman is checked. For childbirth, a set of no more than 15 kg is required. With every extra kilogram, the risk of complications in the development of the fetus increases. Each trimester highlights features that are recorded by the doctor.

The development of twins by week of pregnancy is presented as follows:

1. 1-10. At this time, the body's reaction to pregnancy with twins occurs. This is noticeable by the swelling of the mammary glands, an increase in the level of hCG. By the 8th week, the embryos can be detected by ultrasound - their size is 3 cm. The symptoms are the same as with single pregnancy, but toxicosis occurs earlier. By 10-11 weeks, embryonic development is completed: their length is about 4.5 cm, hearts are formed, weight is 5 g. The voice-forming apparatus is also formed. The faces are different, the heads will be big.
2. 10-20. During this period, both fruits grow rapidly, resulting in a strongenlargement of the uterus and its exit from the pelvic area. It is necessary to wear special clothes for expectant mothers. At week 16, the sex of the children differs, the approximate weight. At this time, babies are able to clench their hands into fists, they have facial expressions, but they almost always sleep. Children have a reaction to sounds, the rudiments of the digestive organs and the excretory system are formed, the intestines work. Babies are able to swallow amniotic fluid and excrete decay products with the bladder. From the 16th week there is a movement of the fetus, from the 20th it is felt clearly. The length of the body of children is 17 cm, and the weight is 200 g.
3. 20-30. Metabolism is noticeably accelerated, stretch marks appear from the growing uterus. Due to the struggle of children in the womb for the correct position, constant tremors occur. The woman has back pain. The discomfort leads to frequent urination, severe fatigue, lower back pain and severe swelling. By week 25, the height of the children is 30 cm, and the weight is 700 g. In appearance, they are similar to newborns. By 28 weeks, babies are viable, and with preterm births, they may have a better chance of survival. By week 30, growth is 35 cm, and the body is fully formed.
4. 30-40. This is an important step. At the 30th week of pregnancy with twins, the formation of the bone skeleton, the development of the pancreas, the accumulation of iron with calcium occur. The head and body will be approximately the same size, so the children will be in proportion. Due to the large belly, it is difficult for a woman to sleep. It is advisable to be on the left side and buy a pillow for pregnant women. At this time, physical restriction is requiredactivity, more rest. At 36 weeks, planned hospitalization is performed. Children at this time are fully full-term: the sucking apparatus is being formed, their height is 45-50 cm, their weight is 2.2-3 kg.

Probable Complications

Considering the topic of how long twins can be identified, one should touch on the issue of complications. Even geneticists are not able to determine the causes of a twin pregnancy, but they are sure that it depends on heredity. It also happens during artificial insemination.

Multiple pregnancies are not detected immediately, and violations and complications are often formed. All consequences are different. By the appearance of the abdomen, it will not be possible to identify violations inside, so regular examinations are needed. The doctor should report all manifestations of pregnancy. Complications can be many, and multiple pregnancies require hospitalization to the clinic, which reduces the risk of harm to the fetus.

Toxicosis is considered a complication and a normal course. Normally, it should flow during 1 trimeter and no more, but if the symptoms are very bright and will occur later, then this indicates a deterioration in the condition.

Other consequences

Preeclampsia is considered a complication of pregnancy, which is characterized by a disruption in the functioning of organs important for the life of children. Typically, such a diagnosis is detected after 20 weeks after the second ultrasound and testing. Preeclampsia comes in 3 forms from mild to severe, and it manifests itself in the form of high pressure, edema, strong secretions.

The appearance of preeclampsia and eclampsia is likely in multiple pregnancies. Depending on the symptoms, it can be high blood pressure, dizziness, flies in the eyes. In this case, hospitalization to the clinic is needed.

Problems include miscarriage, premature birth, the threat of fading of one or both fetuses. To eliminate these consequences, constant testing, examination and implementation of the doctor's recommendations are required.

Conclusion

The article shows all the nuances of how long it takes to identify twins. Although there are generally accepted signs, only a doctor can provide accurate information about the course of pregnancy. Therefore, you need to control your condition only with its help.
