Types of ultrasound of early pregnancy:
• Transvaginal ultrasound - pregnancy is confirmed during the examination using a special probe, which is put on an ultrasound condom and inserted into the vagina. This method is the most accurate and is used for the earliest diagnosis. Ultrasound shows pregnancy as early as 21-22 days from conception.
• Transabdominal. The sensor is applied to the abdomen. Thus, the signal from the uterus needs to travel a greater distance. Therefore, the necessary data can be obtained after another 2 weeks - approximately at the 5th week. In cases where there is a thick layer of subcutaneous tissue, this period increases.
Transvaginal ultrasound should not be performed in the presence of pain and pulling sensations in the lower abdomen, as well as if brown or spotting is disturbing.
At an early stage, pregnancy can be determined by ultrasound with an accuracy of several days, because all babies develop the same way during this period.
During pregnancy, a two-, three-, four-dimensional ultrasound examination can be performed. However, in the early stages, only two-dimensional is used as the safest.
How to prepare for research? Flatulence can affect the clarity of the data obtained - gases can interfere with the structure of the uterus. To avoid this, it is recommended to follow a diet before the study. 3 days before the ultrasound are excluded from the diet:
• legumes;
• cabbage;
• sweet pastries;
• soda;
• fresh fruits.
With transabdominal ultrasound, it is necessary that the bladder is full. One hour before the procedure, drink several glasses of mineral water without gas.
