Hello,
With the question “Uterine ultrasound with negative blank spot but negative HCG test, can I be pregnant? ", the doctor would like to answer as follows:
Beta-hCG is a hormone with a peptide nature, secreted from the trophoblast, which plays the role of activating the embryonic stem cells to develop and mature. is born shortly after the egg is fertilized and begins to implant in the lining of the uterus. At this time, the concentration of HCG will appear in the blood, increasing rapidly until reaching the maximum concentration at two and a half months. Combined with the ultrasound image, there was an empty cyst in the uterus and an increase in size after 2 days. So it is possible to monitor an early pregnancy in the uterus. However, in terms of ultrasound imaging to conclude that the other anechoic sac is a gestational sac, the presence of a yolk sac image is required within that anechoic sac.
Regarding the clinical condition, you have no abdominal pain, no vaginal bleeding, the possibility of ectopic pregnancy is very low. You can monitor your health at home, in about 1 week, you will go for an ultrasound to check again or combine with beta HCG quantification, if the other negative cyst increases in size and combined with the appearance of a yolk sac image. Again, you can safely monitor your pregnancy. If there are any abnormal signs such as lower abdominal pain, vaginal bleeding, .... you need to go to a medical facility with an obstetrics specialist for examination and treatment.
If you still have questions about ultrasound with negative blank spots in the uterus but the HCG test is negative, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
