In most cases, the mucus plug is excreted as a big glob covered with blood stains called bloody show, indicating labor. For others, it may be colorless too.
8. Subchorionic hemorrhage
Chronic membrane is the outermost layer of the amniotic sac. In some rare cases, blood can be formed in between the chorionic membrane and the wall of the uterus leading to spotting or bleeding. This is a concern that requires medical attention.
9. Placenta Previa
Placenta previa a serious pregnancy complication where the placenta grows in the lower part of the uterus covering the cervix.
Brown vaginal discharge is a common symptom of placenta previa and it requires medical attention.
