Background introduction
Giving birth to a new life is something that every couple looks forward to. Pregnancy brings huge physical and psychological challenges to women. If you want to give birth to a healthy baby, timely prenatal check-up and intervention are necessary. As a painless and non-invasive diagnostic tool, B-ultrasound plays a very important role in pregnancy examination. So, how long after pregnancy can you see the gestational sac through B-ultrasound examination?
Gestational sac formation time
The gestational sac is a structure that develops in the early embryo before the placenta begins to form. Generally speaking, the fertilized egg undergoes cell division and movement in the fallopian tube, and finally moves into the uterine cavity. In the uterus, the fertilized egg continues to divide, forming a ball-shaped embryo sac that is a mass of breeding cells. After 2 to 3 days of movement and division, the embryo sac develops into a sac-like structure with a diameter of about 0.1 mm – the gestational sac. The gestational sac is like a gentle protective film that protects the rapidly growing fetus.
The time when the gestational sac was seen through B-ultrasound examination
The gestational sac is formed in the first trimester. If you want to see the gestational sac through B-ultrasound examination, the best time is around 5-6 weeks of pregnancy. Because at this time, the gestational sac will be clearer, complete and obvious in size. At this time, B-ultrasound examination can determine whether there is a gestational sac, and then check the gestational age and fetal health.
Of course, the longer the pregnancy, the more obvious and complete the gestational sac will be, allowing for more accurate detection of gestational age and fetal condition. Around 7-8 weeks of pregnancy, the \”ventricular\”, the so-called heart part of the embryo, will appear in the gestational sac. At this time, the B-ultrasound examination can also see the yolk sac (commonly known as the \”little head\”) in the gestational sac.
Precautions for B-ultrasound examination
Although B-ultrasound examination is a painless and non-invasive examination method, women also need to make corresponding preparations and precautions before the examination to ensure the accuracy and safety of the examination.
The first is the issue of taking medication. B-ultrasound examination needs to be performed 7-14 days after a woman ovulates. If you want to confirm the gestational sac through B-ultrasound examination, you need to stop taking the medicine, otherwise the interference of the medicine will affect the embryo.
Next is the issue of food. You should keep an empty stomach before the examination, and it is generally required to fast for at least 4 hours to ensure clear image performance and avoid misdiagnosis.
Finally, there is the issue of frequency of B-ultrasound examinations. The existence of ectopic pregnancy and other complications during pregnancy and childbirth requires refined and regular B-ultrasound examinations to avoid further aggravation of the condition due to premature or late detection.
Summary
Giving birth to a new life is something that every couple looks forward to. To ensure the health of the fetus, pregnancy testing is very necessary. If you want to check the gestational sac through B-ultrasound in the early stages of pregnancy, it will take about 5-6 weeks. Of course, as the pregnancy progresses, the gestational sac will become clearer and more obvious. The heart part of the embryo that appears around 7-8 weeks of pregnancy is the focus of B-ultrasound examination. In addition, women need to pay attention to medication and diet when participating in B-ultrasound examination to ensure the accuracy and safety of the examination.
