1. When was the first pregnancy ultrasound?
Fetal ultrasound is considered a laboratory test that cannot be missed and is valuable in many aspects during pregnancy. When the pregnancy ultrasound is done at the right time, it is possible to diagnose some dangerous diseases early for both mother and fetus such as: ectopic pregnancy, birth defects... However, not because you want to. detect the above abnormalities that the woman went to ultrasound too early, at only 2-3 weeks of pregnancy. The reason is that in the still young stage of the fetus, under 3 weeks of age, no abnormal signs will be detected because the fetus is too small, in addition, ultrasound in this period also causes some negative effects. to the development of the fetus in the womb.
The process of forming a fetus is said to be from fertilization, after fertilization takes place with the first third of a woman's fallopian tube, at the time of 30 hours later, a zygote will be created and go to the woman's uterus, do the duplication. The duplication of the zygote continues after that until day 5, when the blastocyst is formed. Two days later, the embryo will move and the uterus, buried in the lining of the uterus and begins to implant. At this time, the embryo produces HCG and HCG goes into the urine of the mother, this is also the reason when pregnant, a urine pregnancy test will show 2 lines. So, this is only the embryonic stage of development, so if the ultrasound is too early, it will not work.
To answer the question of when to have the first pregnancy ultrasound, it is necessary to have the necessary signs for the mother to go to the obstetrics facilities for ultrasound, and if pregnant, when the ultrasound is performed in the first 3 weeks Pregnancy will not give any specific results. Therefore, when pregnancy has been confirmed, it is recommended to have a regular pregnancy ultrasound according to the pregnancy ultrasound schedule that the doctor offers, including 3 times of pregnancy ultrasound during the pregnancy to investigate important factors such as measuring the degree of pregnancy. nuchal translucency, finding and detecting pathologies, fetal heart rate, fetal weight, amniotic fluid index ...

Some questions are raised whether the 2-week pregnancy ultrasound gives information about the fetus or not, during this time, the fetus is still not fully developed, so it is still impossible to have a 2-week pregnancy ultrasound. See the shape and development of the fetus. More specifically, after forming the blastocyst as above, at 2 weeks of age, the fetus begins to appear cellular organizations, including 3 layers of cells, the dermis to become parts such as hair. , skin, eyes, nerves, brain, enamel..., the mesoderm will become bone, muscle, kidney, vascular tissue... and the endoderm is the later organs and internal organs.
At the 2-week stage, the fetus does not have the above separate organ tissues, but only a 3-layer cellular organization, which the naked eye cannot recognize, so the ultrasound will not see certain images, sometimes also give incorrect results. In addition, 2 weeks pregnant ultrasound also affects the fetus because the transducer emits sound waves that will not be beneficial to the development of the fetus during this period. Therefore, instead of ultrasound in the first 2 weeks of pregnancy, to know the pregnancy status as well as the fetal status, a woman can use a pregnancy test strip and try it many times in different times for accurate results. best. Besides, a test that is said to be very effective in diagnosing pregnancy is the HCG test, which is a simple, safe blood test for mother and fetus, highly effective in detecting pregnant or not.
