Some thoughts...: In a woman with regular periods, some causes of a late period include: excessive weight loss or gain, increased exercising, emotional stress, having a significant illness, traveling, certain medications, hormonal imbalances, etc… Seeing a doctor is a good idea if symptoms are persistent. Pregnancy is a common cause of a missed period, if having any type of sexual contact.
