my husband seems to have the flu (stuffy nose, coughing, vomiting, 100.4 fever, hot to the touch but he feels cold). The last time he threw up he said there was some blood. He had some cereal for breakfast around 9am, but really nothing else since. I am also about 10 weeks pregnant, so I am trying to keep my distance. My question: should I be concerned about the blood in his vomit?
