8. You’ve Been Bleeding Unusually

A paper cut (or Aunt Flo) will cause you to bleed, but you should not be seeing blood when you go to the toilet, while coughing, or through vomit. Unusual bleeding is a serious health concern at any time. Gastrointestinal issues like hemorrhoids and ulcer will cause blood to appear in your stool or vomit, and blood in the urine could indicate a bladder or kidney infection. Unusual bleeding could even be a caused by certain cancers, especially in the colon or stomach.
