You should call your doctor and ask him/her about that. Sometimes, a yeast infection can cause the skin to become thin and will cause it to break, therefore you would have some blood but it's best to have it checked and INSIST on it. Then you can feel comfortable about what's going on. Make sure you are eating yogurt, staying away from cheeses and milk, yeast products, and drink water to flush it out. Acidolpholus is EXCELLENT in making yeast infections go away. Get it at the health food store.
