In brief: Some thoughts...

In a woman with periods, some causes of a later period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (like birth control pills), hormonal imbalances, etc… seeing a doctor is a good idea if symptoms are persistent, recurring, or worrisome.
Pregnancy is the common cause of a missed period, if sexually active.
