Why do ultrasound on 6th week
An ultrasound at 6-7 weeks pregnant is to determine the fact of "interesting situation." This survey allows you to capture the heartbeat and the outline of the fetus, and to clarify his whereabouts.

Tiny creature in this case becomes the size of small white beans. He still has a little tail, and apparently the embryo is still not too similar to the unborn child.

Pregnancy 7 weeks ultrasound heartbeat
A very important point, which draws the attention of the doctors, is the heartbeat of the fetus. Just how it complies with the standards, and will depend on the physician's verdict. In particular, physicians are interested in three main criteria of assessment:
- the maximum heart rate fluctuations
- the rhythm and frequency of heartbeats
- the nature of the cuts.
For example, assigning obstetric ultrasound on the 7th week of pregnancy, doctors look at the frequency of beats per minute. So, the fetus in 6-8 weeks the little heart is beating with a frequency of not more than 110-130 beats per minute. At 9-12 weeks, the frequency of the beats is in the range of 170-190 beats, and 13-40 for week of 140-160 beats per minute.
In the case if the value is above normal, there is a high probability of the presence of tachycardia. When the frequency of the beats below normal there is a risk of bradycardia. In addition, in the normal development of the fetus his heart rate should be bright, clear and carried out through equal intervals of time.
Upon detection of these deviations is recommended to conduct a thorough examination, followed by the appointment of treatment. Moreover, the first ultrasound done at 7 weeks of pregnancy (as do his, we will explain below), the diagnosis, and then treatment.
How is ultrasound
When getting directions on ultrasound, many women are frankly scared. This happens out of ignorance of the process and its essence. The first should come in the doctor's office, according to the appointed time. You will then be asked to lie down on the couch and expose her stomach.
Thereafter, he put a special gel, which gently spread over the surface of the skin in the area predmostovoy zone. Simultaneously, the technician connects the ultrasound, begins to drive a special sensor in place of the lubricant, and outputs the data to the screen. In the end of this activity the physician able to assess the following points:
- the state and development of the ovum
- the condition and size of the uterus
- the condition of the ovaries.
This inspection is often done at initial stages and during normal pregnancy. In the case if you require a more thorough examination, the case goes the other sensor is for vaginal examination. When working with it specialist, as a rule, puts on his ordinary disposable condom, and then inserts it into the vagina of a pregnant woman. All the necessary information he sees on the monitor screen. As you can see, nothing strange. But whether to do an ultrasound at 7 weeks pregnant or not, you decide.
What you should do before visiting of the doctor-uzist
According to the requirements of doctors, about an hour or two before the ultrasound examination is necessary to drink 1.5-2 liters of water. Accordingly, to go to the hospital is necessary before prescribed time. With them it is recommended to take a small towel, which you will wipe off the gel after the procedure, as well as a condom (in the case of vaginal examination) and obstetric disposable diaper.
What are the concerns about the survey
Fears associated with ultrasound, is often explained by the fear of exposure of the unborn child. According to experts, there is nothing dangerous here. And evidence in the saying of the mass. So, the main argument of the safety of ultrasound is the presence of special sensors able to record and limit the frequency of radiation, so that the waves at this level would not bring harm to the developing baby.
In addition, on the safety of ultrasound say and numerous studies of foreign and domestic experts.
As the fetus in 8 week
Already in the eighth week the unborn child fully formed nervous system and brain. It weighs three grams and growth of 14-20 mm. the baby starts to grow cilia, are formed fingers, and place the bend in the elbows and hands are movable and flexible. The heart increases in size and begins to beat at a speed of 150 beats per minute.

In medical terminology there is such a thing as a timetable for the passage of the ultrasound. What does it mean? This means that during normal pregnancy the future mother needs to make only three UZI:
And while the first survey to examine the woman for pregnancy, study of the normal development of the fetus in order to avoid deviations. He measured the thickness of the nuchal translucency (NT) with the aim of timely detection of chromosomal abnormalities (down syndrome).
During the second inspection, you can determine the sex of a baby. In addition, the doctor examines the placenta, studying blood flow, structure, location, and other characteristics, that allows him to see whether there is a risk of early detachment of the placenta or not.
Third visit of the doctor-uzist will help you calculate specialist exact date of birth, and to re-examine the placenta, in order to detect its possible previa and a deviation from the norm.
