At what date does ultrasound show pregnancy?
Probably every woman who wants to havechild, wants to know as soon as possible, it turned out she has to get 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 to get reliable information that a new life arises within you?
To determine the presence of pregnancy, usuallyconduct 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 the vagina for this ultrasound, the sensor is inserted into the anus. 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 transvaginala 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 only be carried out at an early term of pregnancy. Generally speaking, it's rather difficult to talk about the term of ultrasound on the US, because it depends on many factors.
Less accurate
The transabdominal view of ultrasound suggests thatThe 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 kind of ultrasound is carried out at a later date, then the bladder is not necessarily filled. The accuracy of the transabdominal ultrasound is slightly lower.
At what date does ultrasound show pregnancy?
The egg in which the fetus developsThe transvaginal ultrasound should be noticeable already at the 3rd week of pregnancy. As for the level of hCG, it should be more than 1800 units. If such a level of hCG of the fetal egg in the uterus was not found, then it could be an ectopic pregnancy. How to act in this situation, the doctor can decide only.
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, the fetal egg will not be visible after five weeks, but a little later, although the term for the last menstruation will be quite accurate.
For these reasons, answer the question of manythe question of how long the ultrasound shows pregnancy is somewhat difficult. 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.
