I'm 16 days late, and I have a negative pregnancy test. What are the chances that I'm pregnant and what else could cause my late period?

In brief: Pregnancy unlikely

In a woman with regular periods, some causes of a late 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.
Home pregnancy tests are very accurate 3 weeks after sex.
