Recently, i have missed my period twice?

If sexually active,: Take a pregnancy test. If you miss x 3 get it checked -unless symptomatic.Reasons for missed / late period include: an anovulatory cycle in which no egg is released, marked v or ^ in weight; eating disorder; over-exercising (endurance athletics), travel, significant illnesses, oral contraceptives ; other meds, illegal drug use, breast feeding, hormone imbalances and medical problems (i.e., pcos).
