Becoming a mother is a woman's natural desire, but not always pregnancy is planned. Therefore, if you note a delay in the menstrual cycle of 3-5 days, and there is a probability of fertilization, then it is quite advisable to undergo a transvaginal examination of ultrasound. Most likely, it will show that in your uterus there is already a new "resident" - a 3 mm egg, your future child.
He has already gone through a long and complicated journey, which began with the process of fertilization and passage through the fallopian tubes. You are unlikely to feel any signs of pregnancy, but a 3 mm egg is already inside, is developing and has the full right to life. On the monitor of the ultrasound machine, you can see a drop-shaped or rounded formation that does not reflect ultrasonic waves. At a period of about 2 or 5 weeks, the diameter of the fetal egg is 3-5 mm, it continues to constantly divide its cells and grow. The embryo itself, and its embryonic organs are still so small that they can not be seen in any way. A fetal egg in 3 weeks, as a rule, is attached to the right tube corpus of the uterus, but there are cases of its "low" location, which is not a pathology at all. Just your baby moved for a while in the uterus in search of a haven.
The size of the fetal egg and the gestational age
The ultrasound machine automatically calculates the maximum exact gestation period based on the size of the embryonic chamber. It takes into account the time that was necessary to achieve such parameters and sets the date for the fusion of the male and female eggs. However, obstetrics employs a somewhat different calculation technique, which involves calculating the gestational age from the first day of the last month. As a rule, the error is 2-2.5 weeks and is skimmed during subsequent studies.
If on ultrasound you were told that the size of the fetal egg is 3 mm, then it means that there is time for thinking whether to be this kid or not. Take this dilemma as seriously and responsibly as possible.
