Most cases of brown discharge in early pregnancy are related to preterm miscarriage. If you have brown discharge alone, you should consider that it is caused by low progesterone or poor rest. It is recommended to take a good rest and supplement progesterone, as well as other fetus-preserving drugs. If there is brown discharge combined with stomach pain, inevitable miscarriage should be considered, and ectopic pregnancy should be ruled out. In this case, hospitalization is required for treatment. If ectopic pregnancy is considered, it is an abnormal pregnancy, and this state can lead to more serious complications and requires timely surgical treatment.
