I havent had my period in over 2 months. for the past two days, its felt like im getting my period and its been hinted with a reddish pink color. why?

Likely normal: Periods may be missed or delayed for many reasons, irregular periods are common at the beginnng and end of fertility, and stresses of all sorts, good and not so good (emotional stress, physical stress--dieting, heavy exercise, etc.), can effect the menstrual cycle. If the possibility of pregnancy also exists, this can also make periods stop, consider a pregancy test if it is a possibility.
