It is not uncommon for pregnant women to experience some spotting or light bleeding during the first trimester, including around 8 weeks. While it can be alarming, it is often harmless and does not necessarily indicate a problem with the pregnancy. Brown discharge, in particular, is usually old blood that has taken time to leave the body. However, it is always important to consult your healthcare provider if you experience any bleeding or unusual symptoms during pregnancy. They can evaluate your specific situation and provide guidance based on your individual circumstances.
