If you have brown discharge after pregnancy, you should consider two situations: First, if you have a small amount of brown discharge around the date when you should have your period, you should consider that it is the usual bleeding of the original period, which is not important and you can just observe it without treatment. Second, if there is brown discharge, accompanied by abnormal symptoms such as stomach pain and abdominal cramping, consider the possibility of pre-miscarriage. You need to go to the hospital to check the blood HCG and progesterone levels to see if there is a low progesterone level. If the progesterone level is too low, then observe the amount of bleeding. If the bleeding can stop on its own, it can be treated without treatment and bed rest is good.
