The Fetal Sac Is Still Small And The Fetus Does Not Appear When Ultrasound At 7 Weeks Of Gestation?

I am a 24 year old career woman. My last period was on July 2 2018 so far I have not had a period. I have tested and the results are positive. I checked last night and on the ultrasound, the doctor said that I was 7 weeks pregnant but just now that the pregnancy sacs had not been seen. then I was told to come back in 10 days. in the morning on the same day before check-out I experienced spots but it was not sustainable. the stomach did feel a little bit but it’s not bad I can still move. r ndoctor said that GS was 0.9 cm and it should have been 0.25. I want to ask if there is a serious problem with my pregnancy? why is there no fetus and is normal 0.9 cm GS? thanks doctor. I hope the doctor will always be healthy and be given blessings in the fortune and knowledge of Aamin Ya Rabbal Alamin.

Hi Haifaa,


Thank you for asking HealthReplies.com.

One of the highly recommended tests to ensure pregnancy and to monitor the health of the fetus in the womb is ultrasound. On this examination, you will usually see a gestational sac (at 8 weeks gestation and under) or a fetus (at 8 weeks gestation and over). The size of the gestational sac as well as the fetus can indirectly be an indicator of whether your pregnancy is healthy or not.


If you look at your HPHT date (the first day of your last menstrual period), it is true that your current gestational age ranges from 7 to 8 weeks. At this age, the fetus is often not visible on ultrasound examination because of its very small size. However, to monitor the condition of pregnancy, doctors can use a benchmark gestational sac size as an indicator. At 7-8 weeks gestation, the normal gestational sac size ranges from 20 to 25 mm.


The difference between the calculation of the gestational sac size and the gestational age as you experience it can be normal due to an error in the measurement of the gestational sac or the calculation of gestational age, but it can also indicate other things, for example a blighted ovum (an underdeveloped fetus). Spots from the birth canal that you experience along with minimal abdominal pain can be a normal condition due to the implantation process (implantation of a fertilized product in the uterine wall) or also because of an abnormality, such as a miscarriage.


As your obstetrician recommends, you should ideally have your condition checked again 1 to 2 weeks later. In this way, if it is true that you are pregnant, it is hoped that the size of the fetus is large enough so that it can be more easily detected through an ultrasound examination. However, if there is still no visible fetus, the doctor will do a cross check, whether there is a measurement error, or simply because the fetus is not developing. The next treatment will be adjusted to the conditions you are experiencing.


At this time, you should think more positively. Leave everything that will happen to your life to God Almighty. Rest assured, that God knows best what is best for you and also your partner. Always keep your content, namely by eating healthy and nutritionally balanced foods, reducing instant and preservative foods, increasing vegetables, fruit and foods high in folic acid, and drinking enough water. Also make sure you rest regularly, stay away from stress that is too heavy, and also stay away from cigarettes, alcohol, and illegal drugs.


Hope it helps ..
