Is brown vaginal discharge normal when u r 9 weeks pregnate?

Light Bleeding: Rest assured that in the early weeks of pregnancy, a little spotting or bleeding is very common. The most common cause for experiencing a brown discharge during pregnancy, especially in the later half of the first trimester, is that the body is getting rid of the older blood remnants in the cervix. As the baby grows, the original blood which is used to protect the womb is no longer required.
