Normally, after pregnancy, the level of human chorionic gonadotropin should gradually increase. If it decreases, the doctor may suggest the presence of problems such as:
• In the early stages:
• Fetal death;
• Possibility of spontaneous abortion;
• Absence of an embryo in the fertilized egg;
• At a later date:
• Placental abruption.
In some cases, low hCG levels may be associated with incorrectly calculated gestational age. Therefore, to determine the exact cause of low hormone levels, early pregnancy tests are usually performed, as well as several types of other tests.
