Missed period.: Could be that you have simply missed a period. This occurs for a variety of reasons, stress, exercise, and pregnancy, etc. Missed periods are very common at your age. You have pretty much ruled pregnancy out with a negative hpt at five days after the missed period. If you miss several mor periods you may want to see your doc to figure this out.

Anovulation: You probably did not ovulate the last cycle, which is why your period did not come on time. If controlling your bleeding is the main goal, then pills can be used very effetively. If pregnancy is a goal, then you might need some help ovulating.
