Can do preg. test: Can do a urine preg. Test in 3 days. Pregnancy is the most common cause of a missed period. Other causes of a late or missed period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (especially birth control pills), hormonal disorders, etc… a visit to one’s ob-gyn is a good idea if symptoms are recurring or worrisome.
