My period is 5 days late. i have had negative hpts, but today began having a very dark bloody discharge when i wipe. it has no odor. i'm never late!?

Late period: If your pregnancy tests are consistently negative then you can feel comfortable that you are not pregnant. It is extremely common for women to be late from time to time. This usually works itself out after the next cycle. If not see your obgyn for irregular menstrual cycles.

Agree with Dr. L: Your description is consistent with normal variation in menstrual cycle. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
