Patient's question:
All symptoms: On July 30th, a positive urine test was detected, but no gestational sac was found on ultrasound. On August 5th, menstruation returned again, and the urine test remained positive. hCG levels were 1304, but no gestational sac was found on color Doppler ultrasound. A 18x12 mm mass was detected in the right adnexa. The doctor recommended a follow-up after menstruation clears.Onset time and cause: Got a cold on July 25th and was treated for pregnancy.
Current condition: The cold has improved, and a follow-up is recommended.
Help needed: Whether pregnant or not? If pregnant, why did menstruation return? If not pregnant, why was the test result positive?
Doctor's answer:
The concept of biochemical pregnancy seems to be relatively unfamiliar to many people, and many mothers don't know what a biochemical pregnancy is. If a woman trying to conceive experiences a delayed menstrual period, tests positive with a pregnancy test showing a faint "positive" line, and even has blood tests at the hospital that suggest pregnancy, but her period arrives anyway, it is likely to be a biochemical pregnancy, where she has to part ways with her baby.In fact, biochemical pregnancy is an early miscarriage, typically occurring around the fifth week of pregnancy. However, the condition within the body during this period cannot be detected by ultrasound scans. This process involves sperm fertilizing an egg, but the egg does not survive afterward. Ultrasound examinations fail to detect a gestational sac, indicating that the fertilized egg has failed to implant, which is also known as "subclinical miscarriage."
