A biochemical pregnancy is an early loss of pregnancy that usually occurs a few days after a positive pregnancy test. It is quite difficult to determine the cause of biochemical pregnancies, since the embryonic tissue is expelled with menstruation and therefore cannot be analyzed.
Even so, in many cases, spontaneous miscarriages are due to problems with the embryo, possibly caused by low-quality sperm or eggs.
Other possible causes may include:
- Abnormal hormone levels.
- Uterine abnormalities.
- Implantation outside the uterus, that is, ectopic pregnancies.
- Sexually transmitted infections.
- Advanced maternal age.
- Blood clotting issues and thyroid disorders.
In any case, it is not recommended to try to identify the possible cause of the biochemical pregnancy. Some embryos are simply not capable of developing.
