At this stage, only the prerequisites for the appearance of the fetus arise, and successful fertilization, which can occur in about two weeks, depends on many factors. Accordingly, ultrasound of the fetus at this time is not done. It should be noted that even in the first days of pregnancy (meaning the embryonic period), there are no reliable ways to confirm successful conception.
With the help of ultrasound in the first weeks of pregnancy on the 1st, 2nd, 3rd and 4th day of delay, it is most likely impossible to determine the presence of an embryo. The fetus in this study can be seen approximately on the 5th or 7th day of the delay in menstruation. The level of the hCG hormone (chorionic gonadotropin), which is produced in a woman's body during pregnancy, does not increase in the early stages, so on the first day of the delay, the test may also not show two cherished strips. Positive results can be detected only from 12-14 days after the conception of a child.
