At 7 weeks pregnant, how does the length of the gestational sac not corresponding to the embryo improve?

Question
Hello doctor,
I'm 7 weeks pregnant with ultrasound, 16mm gestational sac, 10mm head and buttocks length, 146 fetal heart rate, I have a miscarriage. The doctor said that the gestational sac does not correspond to the embryo, if the gestational sac does not develop, the pregnancy will be stopped. So the doctor asked me how does the 7 week old pregnancy with the length of the gestational sac not corresponding to the embryo improve? Thank you.

Hello,
With the question “How does 7 weeks pregnant with gestational sac length not corresponding to embryos improve? ", the doctor would like to answer as follows:
7 weeks pregnant, the length of the head and buttocks is 10mm, the fetal heart rate is 146 times / minute is normal. The length of the gestational sac does not correspond to the length of the embryo, but the ratio between the gestational sac and the embryo is still above 5mm, so the fetus can still develop normally. Therefore, you should go back for another ultrasound after 1 week.
Ultrasound is best done when the bladder is not full (except in cases of transabdominal ultrasound in early pregnancy). Therefore, it is necessary to urinate before the ultrasound. Do not apply body lotion/oil for 48 hours prior to the ultrasound. Ultrasound is painless. However, in some cases, the doctor presses the transducer slightly, which can cause discomfort.
In addition, the first 3 months are the most sensitive time during pregnancy. In order for mother and baby to be healthy, you need to note:
Understand early signs of pregnancy, pregnancy poisoning, bleeding during pregnancy. Timely, correct and sufficient first prenatal check-up, avoiding too early/too late. Fetal malformation screening at 12 weeks detects dangerous fetal malformations that can be intervened early. Distinguish between normal vaginal bleeding and pathological vaginal bleeding for timely intervention to maintain pregnancy. Screening for thyroid disease in the first 3 months of pregnancy avoids dangerous risks before and during delivery. Vinmec currently has many maternity packages (12-27-36 weeks), in which the 12-week maternity package helps monitor the health of mother and baby right from the beginning of pregnancy, early detection and timely intervention of health issues. In addition to the usual services, the maternity monitoring program from 12 weeks has special services that other maternity packages do not have such as: Double Test or Triple Test to screen for fetal malformations; Quantitative angiogenesis factor test to diagnose preeclampsia; thyroid screening test; Rubella test; Testing for parasites transmitted from mother to child seriously affects the baby's brain and physical development after birth.
If you still have questions about the fact that the 7 week old pregnancy has a gestational sac length that does not correspond to the embryo, you can go to a hospital under Vinmec Health System to check. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
