Bearing several fruits is called multiple pregnancy. This situation is much more complicated than with the development of one child. You should try to save the kids. How long can twins be identified? The answer to this question is presented in the article.
Signs
Usually the symptoms of early pregnancy are the same anyway. But with double, deterioration and the appearance of new signs can be noticeable. But only a doctor can identify who develops - a son, daughter or twins.
Two-pregnancy can be detected by:
severe toxicosis;
the presence of bright stripes on the test, since the level of hCG hormone increases markedly;
a rapid increase in the abdomen during pregnancy with twins;
early manifestation of baby movements;
rapid weight gain, especially in the 1st trimester;
high appetite
sharp and serious mood swings.
There is still a need for exotic fruits and unusual foods, because you need more vitamins and minerals. And the body is looking for them in food.
Symptoms of Twins
Multiplicity can be determined on their own. But it is better to get an ultrasound scan. The double procedure is sure to show. Inspection helps to note such manifestations as an enlarged uterus, which, for example, at 5 weeks can correspond to 9 weeks. Blood donation for the hCG hormone will be required. If a high indicator is detected, then this will be another sign.
Blood is examined for iron, alpha-fetoprotein. When the uterus is twins, the amount of iron is reduced, and the ACE protein is increased. It will be possible to determine the presence of 2 fruits on the basis of listening to 2 heartbeats, as well as probing 2 heads, but this is possible only in the later stages.
To exclude a medical error, an ultrasound scan is required. 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?
How long 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 - twins - boys or girls can also be determined by a doctor.
But, according to experts, you should not trust this result. A second study will be required at week 12, as the risk of killing 1 fetus is very high. According to statistics, only 5 out of 10 women survive both children. This is affected by the physiology or health of the body.
Identical twins
How are identical twins determined? Must pass:
examination by a doctor;
pregnancy test;
Ultrasound
The identical twins are visible at week 12, not earlier. After determining this, after 3 weeks you need to perform a secondary study to confirm the viability of the fruit.
Frequent ultrasound procedures do not harm children, because now only modern technologies are used. They allow you to accurately track the condition of the fruits and their development.
Manifestation of multiple pregnancy
Ultrasound is not noticeable: the 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 single pregnancy is markedly different from a multiple pregnancy, and the second is diagnosed in different ways.
Diagnostics is performed as follows:
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.
A history of menstrual function is being examined. The doctor needs to be told when there were periods, whether the cycle is regular, and how it goes.
You will need the results of a test done at home.
Blood testing for hCG hormone is being performed.
A gynecological examination is performed, in which an increase in the volume of the uterus is detected.
An ultrasound of the pelvic organs is also performed. Ultrasound is usually prescribed before 11 weeks if there are problems with miscarriage, fetal freezing, ectopic pregnancy. In other situations, a planned study of the body is required.
Development
During pregnancy, twins women are included in the high-risk group, therefore, special supervision by doctors is required. To do this, go to the antenatal clinic: every 14 days to 28 weeks, and then after 7-10 days.
During each examination, the weight of the pregnant woman is checked. A delivery of not more than 15 kg is required for childbirth. With every extra kilogram, the risk of complications in the development of the fetus increases. Each trimester highlights the features that are recorded by the doctor.
The development of twins by week of pregnancy is as follows:
1-10. At this time, the body reacts to a twin pregnancy. This is noticeable by the swelling of the mammary glands, an increase in the level of hCG. By week 8, the embryos will be able to be detected by ultrasound - their size is 3 cm. Symptoms are the same as with monopodia, but toxicosis occurs earlier. By 10-11 weeks, embryonic development is completed: their length is about 4.5 cm, the formation of hearts takes place, their weight is 5 g. A voice-forming apparatus is also formed. Faces differ, heads will be large.
10-20. During this period, both fruits grow rapidly, which leads to a strong increase in the uterus and to its exit from the pelvic area. It is necessary to wear special clothes for expectant mothers. At week 16, the gender of the children is different, the approximate mass. At this time, the kids are able to squeeze their hands into fists, their facial expressions come to light, but they almost always sleep. In children, a reaction to sounds appears, the rudiments of the digestive system and excretory system are formed, the intestines work. Toddlers are able to swallow amniotic fluid and excrete decay products from the bladder. From 16 weeks the movement of the fruit is observed, from 20 it is felt clearly. The body length of the children is 17 cm, and the mass is 200 g.
20-30. Metabolism is noticeably accelerated, stretch marks occur from the growing uterus. Due to the struggle of children in the womb for the correct position, constant tremors arise. A woman has a backache. Inconvenience leads to frequent urination, severe fatigue, low back pain and severe swelling. By week 25, children are 30 cm tall and weigh 700 g. They look like newborns. By week 28, babies become viable, and with premature birth can be more likely to survive. By week 30, growth is 35 cm, and the body is fully formed.
30-40. This is an important stage. At the 30th week of twin pregnancy, the formation of the bone skeleton, the development of the pancreas, the accumulation of iron with calcium. The head and body will be approximately the same size, so the children will be proportional. Due to the large abdomen, 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, restriction of physical activity is required, more rest. For 36 weeks, planned hospitalization is performed. Children at this time are completely full-term: a sucking apparatus is formed, growth is 45-50 cm, weight - 2.2-3 kg.
Probable complications
Considering the topic at what period twins can be determined, one should touch on the issue of complications. Even genetics are not able to determine the causes of a double-egg pregnancy, but they are sure that it depends on heredity. This also happens with artificial insemination.
Multiple pregnancy is not determined immediately, while violations and complications often form. All consequences vary. By type of abdomen, it will not be possible to identify abnormalities inside, therefore, regular examinations are necessary. The doctor should report all manifestations of pregnancy. There can be many complications, and with a multiple pregnancy, hospitalization in a clinic is necessary, which reduces the risk of harm to the fetus.
Toxicosis is considered a complication and a normal course. Normally, it should occur during 1 trimester and no more, but if the symptoms are very bright and will occur later, then this indicates a worsening of the condition.
Other consequences
Preeclampsia is considered a complication of pregnancy, which is characterized by a malfunction of organs important to the life of children. Typically, such a diagnosis is detected after 20 weeks after performing a second ultrasound and passing tests. Gestosis occurs in 3 forms from mild to severe, and it manifests itself in the form of high pressure, edema, strong discharge.
The appearance of preeclampsia and eclampsia is likely with multiple pregnancy. Depending on the symptoms, it can be high blood pressure, dizziness, flies in the eyes. In this case, hospitalization in the clinic is needed.
Problems include miscarriage, premature birth, the threat of fading of one or both fetuses. To exclude these consequences, constant testing, an examination and the implementation of the doctor's recommendations are required.
Output
The article indicates all the nuances of how long twins can be determined. 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.
