You may want to wear panty liners during that time. The things to be worried about include if the discharge has a yellow or green color, is clumpy like cottage cheese, or has a bad odor. If you are worried, see a doctor. If you have spotting at the time of your normal period rather than your usual amount of flow, and you have had sex without using birth control, you should check a pregnancy test.
