What are the symptoms of biochemical pregnancy?

Patient's question:

What are the symptoms of biochemical pregnancy?

Doctor's answer:

Generally, after the sperm and egg combine for seven days, human chorionic gonadotropin (hCG) starts to be secreted. Seven days later, a pregnancy test can detect it, but it is essential that the sperm and egg combine to form a fertilized egg, which then implants in the uterus. However, biochemical pregnancy occurs when the sperm and egg combine, but the fertilized egg does not return to the uterus for implantation, or it returns but fails to implant successfully, resulting in it being shed along with the menstrual flow.
So, what symptoms can indicate biochemical pregnancy?
1. A pregnancy test may show a faint positive but is unlikely to reach a positive or strong positive.
2. An ultrasound cannot detect a gestational sac in the uterus.
3. Blood hCG levels are very low, indicating pregnancy but not whether implantation was successful.
4. It usually does not last beyond 50 days and results in the natural expulsion of grayish-white membrane-like discharge.
For those familiar with pregnancy test strips, please note that under normal circumstances, a faint positive can be detected 12 days after ovulation. Subsequent changes may vary: some may see the test color deepen every other day, while others may notice a clear intensification daily. If there is no such deepening trend for three or more consecutive days, the embryo is likely problematic.
Biochemical pregnancy refers to the condition where a fertilized egg fails to return to the uterus for implantation. This is generally a normal occurrence, part of natural selection, and there is no need to worry. However, if this happens repeatedly, it is advisable to actively investigate the underlying causes.
