At what time does ultrasound show pregnancy?

Probably, every woman who wants to have a child wants to know as soon as possible whether she got pregnant or not. As everyone knows, pregnancy tests and hCG tests have a certain error, so the most accurate way to determine pregnancy is ultrasound (hereinafter - ultrasound). But at what time does ultrasound show pregnancy? When is it best to go to research in order to get reliable information that a new life arises within you?

Types of ultrasound and their accuracy

To determine the presence of pregnancy, usually carry out ultrasound of the organs in a small pelvis. To date, several types of ultrasound are used: transrectal, transvaginal, transabdominal and combined. Transrectal is done to girls who do not yet have sex. Instead of a vagina at the given US the gauge is entered into an anal aperture. But we are interested in other species, since we want to find out on what term ultrasound determines pregnancy.

The most accurate

The most accurate of all is the transvaginal type. In his process, the sensor, on which the condom is preliminarily put on, is injected into the vagina. There must be a completely emptied bladder to get the most accurate result. This type of ultrasound can be performed only at an early pregnancy. In general, it is rather difficult to talk about how long the ultrasound will show pregnancy, because it depends on many factors.

Less accurate

Transabdominal ultrasound suggests that the examination is done through the abdominal wall (front). If such a study is conducted in a girl who is not pregnant, then her bladder should be complete. If this type of ultrasound is performed at a later date, then the bladder is not necessarily filled. The accuracy of the transabdominal ultrasound is slightly lower.

Combined ultrasound suggests a combination of transvaginal and transabdominal species. It is not difficult to guess that if ultrasound can determine if you are pregnant or not as early as possible, you should use a transvaginal ultrasound.

At what time does ultrasound show pregnancy?

The egg, in which the fetus develops, during transvaginal ultrasound should be visible already at 3 weeks of pregnancy. As for the level of hCG, it should be more than 1800 units. If no such a level of hCG of the fetal egg in the uterus was found, then it could be an ectopic pregnancy. How to act in this situation, the doctor can decide only.

Are there any errors?

Even ultrasound has its own degree of error. On what term ultrasound shows pregnancy, depends on whether ovulation came on time, and on the exact date of conception. As a rule, such details can not be determined, so the error can be large. On ultrasound, for example, a fetal egg will be seen not in five weeks, but a little later, although the term for the last menstruation will be quite accurate.

For these reasons, it is somewhat difficult to answer the question of interest to many on the term of ultrasound during pregnancy. At someone it will be determined already in 3 weeks, and at someone - in 7 weeks. If ultrasound does not determine pregnancy, but, as you think, should, then do not get upset. Yet, even ultrasound can not be completely accomplished, in addition, as we found out, they have some degree of subjectivity.
