In what period an ultrasound shows a pregnancy
Probably every woman who wants to have a baby, want as quickly as possible find out she's pregnant or not. As everyone knows, pregnancy tests and HCG tests have a certain margin of error, so the most accurate way to determine pregnancy is an ultrasound study (hereinafter the USG). But in what period an ultrasound shows a pregnancy? When is the best time to go to study to obtain reliable information about what's inside you brand new life?
To determine the presence of pregnancy, is usually carried out ultrasound examination of the organs in the pelvis. Today used several types of ultrasound: transrectal, transvaginal, transabdominal, and combined. Transrectal produce girls who do not live a sexual life. Instead of the vagina with the ultrasound transducer inserted into the anus. But we are interested in other types, since we want to find out what period an ultrasound detects pregnancy.
The most accurate of all is the vaginal type. Its sensor, which previously put on a condom, inserted into the vagina. There should be completely empty the bladder to obtain the most accurate result. This type of ultrasound can only be performed early in pregnancy. In General, talking about at what time an ultrasound shows a pregnancy is difficult, because it depends on many factors.
Transabdominal ultrasound involves the view that the study is done through the abdominal wall (front). If such a study is carried out on a woman who is not pregnant, her bladder must be full. If this kind of ultrasound is done at a later time, then the bladder to fill, is not so sure. The accuracy of transabdominal ultrasound view below.
Combined ultrasound involves a combination of transvaginal and transabdominal. It is easy to guess that ultrasound was able to determine you are pregnant or not as early as possible, you must use the transvaginal kind of ultrasound.
In what period an ultrasound shows a pregnancy?
The egg in which the fetus, transvaginal method should be already noticeable at 3 weeks pregnant. As for the level of HCG, it should be more than 1800 units. If so the HCG levels gestational SAC in the uterus was not discovered, it could be an ectopic pregnancy. What to do in such a situation, can only solve the doctor.
Even the UZI has its own degree of error. In what period an ultrasound shows pregnancy depends on whether the time has come ovulation, and the exact date of conception. Typically, such items cannot be determined, so the error can be large. On the ultrasound, for example, will be seen fertilized egg not five weeks, but a little later, although last menstrual period period is pretty accurate.
For these reasons, the answers to many question about what time an ultrasound shows pregnancy somewhat difficult. For some, it will be set at 3 weeks, and someone- in 7 weeks. If ultrasound has not detected a pregnancy, but what do you think, should there, then do not worry. Still, even an ultrasound can't be completely perfect, in addition, as we have seen, they have some degree of subjectivity.
