A delay of 2–3 days can occur occasionally even if your periods are usually regular, due to stress, changes in sleep, weight, illness, travel, or hormonal fluctuations. However, if you have had unprotected intercourse or any contraceptive failure, pregnancy must first be ruled out. Light spotting alone cannot confirm or exclude pregnancy.
Next Steps
Do a home urine
pregnancy test, preferably with first-morning urine.
Health Tips
Do not take medicines to induce a period until pregnancy has been excluded. Seek urgent medical care if you develop severe lower abdominal pain, heavy bleeding, dizziness, or fainting.
