Missed Period & Pregnancy: What to Know & When to Test

Missing a period is a common early sign of pregnancy, but not all missed periods indicate pregnancy. Stress, illness, hormonal imbalances, weight changes, and certain medications can also cause a missed period.

Confirming Pregnancy

If you miss a period and suspect pregnancy, consider these steps:

1. Home Pregnancy Test

• Widely available, providing quick and accurate results.
• Detect human chorionic gonadotropin (hCG), a hormone produced by the placenta.
• Most tests can be used from the first day of a missed period; some sensitive tests may detect hCG earlier.

2. Blood Test

• Measures hCG levels in the blood.
• Can detect pregnancy earlier than urine tests, sometimes before a missed period.
• Quantitative blood tests (beta-hCG) track hormone levels over time, useful for monitoring early pregnancy viability.

When to See a Doctor

If a home test is positive, or if you have a missed period with other pregnancy symptoms (breast tenderness, nausea, fatigue), schedule an appointment with a healthcare provider to confirm pregnancy and begin prenatal care. Early prenatal care improves outcomes for both mother and baby.

Key Takeaway

There is no fixed number of days a period must be missed to confirm pregnancy. A missed period may be the first sign for some, while others may not notice until later. When in doubt, take a home test or consult a doctor.
