Pregnancy Term & Due Date: Understanding the Timeline

A full-term pregnancy typically spans around 40 weeks, starting from the first day of your last menstrual period (LMP). This estimate includes approximately 38 weeks from conception, aligning with medical standards globally. According to the World Health Organization (WHO), a normal pregnancy can last anywhere from 37 to 42 weeks, with delivery often occurring naturally within this window. During your first OB-GYN visit, your doctor may calculate an estimated due date (EDD) using either an early ultrasound scan or your menstrual cycle history. While these methods are reliable, individual factors—such as maternal age, previous pregnancy durations, and biological variability—can influence the actual delivery date. Interestingly, medical research shows:
Fewer than 4% of births occur exactly on the estimated due date
About 60% take place within one week of it
Nearly 90% happen within two weeks
This makes due dates best viewed as guidelines, not guarantees.

Early Signs & Detection of Pregnancy

Pregnancy is often first identified through physical symptoms or testing. Common early signs include:

• Missed periods
• Mild nausea or morning sickness
• Fatigue
• Breast tenderness
• Higher basal body temperature
• Increased urination

To confirm pregnancy, most women opt for home urine tests or clinical blood tests. Blood tests detect the hormone hCG (human chorionic gonadotropin), often as early as 6-8 days after fertilization. While blood tests are more accurate and sensitive, urine tests remain popular for their accessibility and affordability.
Clinical guidelines suggest seeking confirmation through lab testing and scheduling an early prenatal checkup to begin monitoring the pregnancy accurately.

Pregnancy Management: What to Consider

Pregnancy involves changes that affect every aspect of a woman’s health. Careful management of medications, weight gain, exercise, and nutrition is crucial for a healthy outcome.
