The blood is not what is abnormal, it is the purging behaviors. Our bodies are not meant to purge up the food we eat (unless it is a natural reaction to being sick or eating something that does not agree with our body). If you see blood while you are purging it may be a sign of a ruptured esophagus or other internal bleeding, especially since it is not bright red.
The only advice I have for you is to stop purging and seeking professional help. If after two weeks you have purged enough to make yourself bleed, that is a significant problem. Purging in itself is a significant problem. Please seek the help you need. A professional can help you recover and discover a more adaptive relationship with food.
