why is my period lighter
A lighter period than normal can be caused by many things, including pregnancy, stress, illness, and other things. Sometimes a woman will have spotting and think her period is about to start and not see any more bleeding. This is usually implantation bleeding that has been mistaken for a menstrual cycle.
Light menstrual periods, sometimes referred to as oligomenorrhea, can be normal, but they can also mean that a woman is experiencing hormonal changes or the effects of medical conditions, poor nutrition or stress on the body.
