Picture of 7-week gestational sac size

After pregnancy, the gestational sac will be seen in the B-ultrasound examination, which means that it is a normal pregnancy in the uterine cavity. It will gradually turn into a test tube embryo when the month comes, and then become a perfect fetus. This is a very long process. After checking, many expectant mothers place orders carefully. So how much does the standard price of a gestational sac at seven weeks of pregnancy cost?

Generally, the fetal sac can be found in the uterine cavity by vaginal B-ultrasound at five weeks of pregnancy, while abdominal B-ultrasound takes about six weeks. At seven weeks of pregnancy, the gestational sac in the uterine cavity is approximately 27.2 mm, and there will be a significant yolk sac, fetal bud and initial primitive heart tube beating heartbeat in the gestational sac. The fetal sac is not very stable in the early stages of pregnancy, so try not to have sex, bend your head, exert force, or overexert yourself, which can easily lead to threatened miscarriage. In addition, you need to actively take folic acid until the 12th week of pregnancy to effectively prevent neural tube defects in the fetus.

After having a certain understanding of the gestational sac, let's discuss the issues related to the gestational sac. In daily life, there are mainly two types of problems related to the gestational sac: empty gestational sac and small gestational sac. An empty gestational sac means that the test tube embryo has not developed well. There are many reasons, such as poor sperm quality and environmental factors that affect the development of the embryo. Sometimes an empty gestational sac will appear due to late sperm and egg combination. Therefore, couples should improve the quality of sperm, refrain from smoking and drinking, increase physical exercise, and maintain a good mood during the active preparation for pregnancy.

Due to incomplete development of sperm and egg cells, infection of chlamydia, mycoplasma, rubella virus during pregnancy, or exposure to harmful substances during pregnancy, the fetal sac may be incompletely developed and shorter than normal. The fetal sac in this case is unhealthy and will eventually cause miscarriage. When facing this kind of situation, prospective parents must understand the actual reasons for the small fetal sac, work hard to improve their physical fitness during pregnancy, maintain a happy mood, avoid harmful substances, and avoid pathogens.
