- Transabdominal ultrasound. Performed through the anterior abdominal wall and is the main method of ultrasound examination during pregnancy. It is used at different stages and allows assessment of fetal development, its position, heartbeat, as well as the condition of the uterus, placenta, and amniotic fluid.
- Transvaginal ultrasound. Performed using a vaginal probe and is most often used in early pregnancy. This method provides more detailed visualization at the initial stages, helps confirm intrauterine pregnancy, assess the condition of the embryo, and early stages of its development.
Pregnancy ultrasound
Ultrasound during pregnancy is an important examination that helps monitor the development of the unborn child from the first weeks until delivery. Using ultrasound diagnostics, the doctor can assess the condition of the fetus, uterus, and placenta, track key stages of development, and timely detect changes that require medical attention.
At the medical center «Oxford Medical», ultrasound examinations are performed using modern expert-class equipment, which ensures high accuracy and informative results. Doctors pay attention not only to the quality of diagnostics but also to clear explanations of the examination results so that the patient fully understands her health condition and the specifics of the pregnancy course.
You can schedule an ultrasound for pregnant women at a convenient time through the call center or the online appointment form on the website. In our private clinic, you can undergo an ultrasound or a full gynecological check-up in comfortable conditions and receive a conclusion from experienced specialists.
Why Ultrasound Is Performed During Pregnancy
The method of ultrasound diagnostics is based on the use of high-frequency sound waves that pass through body tissues and are reflected from internal structures. Based on the received signals, an image is formed that allows the doctor to assess the condition of the fetus.
During the examination, fetal heart activity, motor activity, and other parameters important for monitoring the course of pregnancy are determined. This makes it possible to timely detect potential changes and determine the need for additional monitoring or correction.
Ultrasound during pregnancy is performed in order to:
- confirm the presence of pregnancy and ensure that it is developing in the uterus;
- уточнить срок беременности и рассчитать ориентировочную дату родов;
- assess fetal heart activity and the overall state of its development;
- check whether the child’s development corresponds to the gestational age;
- assess the condition of the uterus, placenta, and amniotic fluid;
- timely detect possible deviations or complications of pregnancy;
- determine further medical observation tactics.
Regular ultrasound examinations help the doctor monitor the course of pregnancy, and help the expectant mother better understand how the baby is developing at each stage and feel calmer while waiting for the baby.
Types of Pregnancy Ultrasound
During pregnancy, ultrasound examination may differ both by the method of performance and by visualization modes. The specific ultrasound option is chosen by the doctor taking into account the gestational age, clinical situation, and purpose of the examination.
By Method of Performance
By Ultrasound Assessment Modes
- Doppler ultrasound for pregnant women is used to assess blood flow in the vessels of the fetus, placenta, and uterine arteries. The examination makes it possible to determine how effectively placental circulation is functioning and to timely detect disorders that may affect the child’s development.
- 3D ultrasound makes it possible to obtain a three-dimensional image of the fetus. It is used as an addition to standard ultrasound for a more detailed assessment of individual anatomical structures on the doctor’s recommendation.
- 4D pregnancy ultrasound is a type of volumetric visualization in which the fetal image is displayed in motion. This format allows observation of the baby’s motor activity and provides additional information about the specifics of its development.
When Ultrasound Is Needed During Pregnancy
Pregnancy ultrasound screening is performed at specific times in accordance with clinical protocols.
Planned ultrasounds during pregnancy:
Ultrasound: first screening (11–13 weeks of pregnancy)
This is usually the first ultrasound during pregnancy. At this stage, the doctor уточняет срок беременности, determines the number of fetuses, assesses fetal heart activity, motor activity, and basic anatomical structures.
Ultrasound: second screening (18–22 weeks of pregnancy)
This is one of the most informative stages of ultrasound monitoring. During the examination, fetal anatomy, development of major organs and systems, condition of the placenta, volume of amniotic fluid, and the baby’s position in the uterus are evaluated in detail. Also, at this time ultrasound determination of the baby’s sex is usually performed.
Ultrasound: third screening (30–34 weeks of pregnancy)
Performed to assess fetal development, its position before delivery, the condition of the placenta, and features of blood supply. The obtained data are important for further pregnancy management and preparation for childbirth.
Unscheduled Ultrasound Examination
In addition to planned examinations, the doctor may prescribe an unscheduled ultrasound if complaints appear or if there are other medical indications.
Unscheduled ultrasound may be recommended in cases of:
- pain in the lower abdomen or the appearance of bloody discharge;
- suspected fetal development disorders;
- changes in the pregnant woman’s well-being that require clarification of causes;
- the need to monitor the condition of the placenta or amniotic fluid;
- the presence of concomitant diseases or pregnancy complications.
Strict adherence to the recommended timing of fetal ultrasound and completion of additional examinations as prescribed by the doctor allows for comprehensive medical monitoring and timely response to any changes during pregnancy.
How to Prepare for Pregnancy Ultrasound
Preparation for ultrasound examination depends on the gestational age and the purpose of the examination. In most cases, it is simple.
When ultrasound is performed in early pregnancy, the doctor may recommend coming to the examination with a moderately full bladder, as this improves visualization of the uterus and allows more accurate assessment of the pregnancy course.
Starting from the second trimester, special preparation is usually not required. Planned ultrasounds for pregnant women are performed without restrictions on diet or fluid intake.

Frequently Asked Questions
At what stages of pregnancy is ultrasound performed?
Ultrasound during pregnancy is performed both routinely and for medical indications. Standard examinations are carried out three times: in the first trimester (11–13 weeks), second trimester (18–22 weeks), and third trimester (30–34 weeks). If necessary, the doctor may recommend additional ultrasounds to уточнить fetal condition or the course of pregnancy.
Can ultrasound detect amniotic fluid leakage?
Amniotic fluid leakage cannot be directly detected on ultrasound. However, the doctor can assess the amount of amniotic fluid and identify its reduction, which may indicate a potential problem. Additional clinical and laboratory methods are used to confirm leakage.
Will ultrasound show pregnancy at 1–2 weeks?
At 1–2 weeks after conception, ultrasound usually does not allow visualization of pregnancy. During this period, the embryo is still too small. Most often, pregnancy becomes visible on ultrasound from approximately 4–5 obstetric weeks, when the first signs of the gestational sac appear.
At what stage does ultrasound show pregnancy?
In most cases, pregnancy can be confirmed by ultrasound from 4–5 weeks of obstetric age. At this time, the gestational sac is visualized in the uterine cavity. Clearer signs, including fetal heart activity, are detected somewhat later, usually from 6–7 weeks.
How many times is ultrasound performed during pregnancy?
The number of ultrasounds depends on the course of pregnancy and medical indications. In the absence of complications, three planned ultrasound examinations are usually performed. If complaints arise or dynamic monitoring is required, the doctor may prescribe additional examinations.
At what week can the baby’s sex be seen on ultrasound?
The fetal sex can usually be determined during ultrasound in the second trimester, approximately from 18–20 weeks of pregnancy. At earlier stages, the sexual characteristics are not yet sufficiently formed, so assessment may be inaccurate or impossible.
Can pregnant women eat before an ultrasound?
In most cases, there are no dietary restrictions before ultrasound during pregnancy. Exceptions may include specific recommendations from the doctor depending on the gestational age and type of examination.
Why might pregnancy not be visible on ultrasound?
Pregnancy may not be detected on ultrasound due to a very early stage, особенностей menstrual cycle, or later ovulation. The quality of the equipment and the examination method are also important factors. In such cases, the doctor usually recommends a repeat ultrasound in early pregnancy or additional tests.
Does ultrasound affect fetal development?
Ultrasound examination does not use ionizing radiation and is considered a safe diagnostic method during pregnancy. It has been used in worldwide medical practice for many years.
