QuestionHi doctor,
I just had my first antenatal checkup, I had a private examination with a black and white ultrasound, the doctor said I am 5 weeks pregnant but only have an 11mm gestational sac, haven't found anything yet and won't give me any advice on whether I should be examined. again or not. Doctor let me ask if such a fetus is developing correctly? How does the size of the gestational sac indicate the status of the embryo?

Hello,
With the question “How does the size of the gestational sac indicate the status of the embryo? ", the doctor would like to answer as follows:
In your case, currently the ultrasound doctor calculates the gestational age according to the size of the gestational sac. With a gestational sac of 11mm or less, the condition that the embryo cannot be clearly seen is also common. If you have no abnormal clinical signs, your menstrual cycle is regular and on ultrasound, the gestational sac is regular, there is no fluid collection, and dissection around the gestational sac, the obstetrician will calculate the gestational age according to the date of the last menstrual period. around 5 weeks.
You can maintain a normal pregnancy according to the instructions of the obstetrician and follow-up ultrasound after about 07 - 10 days, you can see the embryo as small as 03 - 04mm, see if the embryo has a fetal heart.
If you still have questions about the size of the gestational sac, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
