The bleeding in early pregnancy is not necessarily due to low progesterone. If the embryo itself is not of good quality or the pregnant woman is not resting well, the endometrium is too thin, the uterus is developing abnormally or other comorbidities may affect the development of the fetus, and the early pregnancy is a high-risk period for miscarriage. If the embryo is not developing well, it will be eliminated naturally through miscarriage during early pregnancy. Therefore, we should continue to observe the current situation and pay attention to rest, and use fetal preservation drugs under the guidance of the doctor. If the embryo is developing well, you can continue to keep the pregnancy, but if the embryo is not developing well, you should consider terminating the pregnancy.
