When you puked today it was mostly mucus and after the there a little blood?

If you are experiencing vomiting of mucus and blood, it is important to seek medical attention. Vomiting blood can be a sign of a serious underlying medical condition, such as a gastrointestinal bleed or stomach ulcer. Vomiting mucus can also be a sign of an infection or other medical condition. Seeking medical attention will allow a healthcare professional to properly evaluate your symptoms and provide appropriate treatment. Self-treating vomiting with mucus and blood is not recommended, as it could delay or compromise necessary medical care.
