Pregnancy Due Date Calculator & Term Guide: Your Journey to Motherhood
Welcome to your comprehensive guide to understanding pregnancy terms and estimating your baby's due date! Pregnancy is a remarkable journey, a period of approximately nine months during which one or more offspring develop inside a woman. Our tools and information are here to help you navigate this exciting time.
What is a Full-Term Pregnancy?
A typical pregnancy lasts about 38 weeks from conception or, more commonly calculated, about 40 weeks (280 days) from the first day of your last menstrual period (LMP). The World Health Organization (WHO) defines a normal pregnancy term as lasting between 37 and 42 weeks.
How is My Due Date Calculated?
During your first OB-GYN visit, your doctor will provide an estimated due date. This date can be determined in several ways:
Last Menstrual Period (LMP)
Most common method. Add 40 weeks (280 days) to the first day of your LMP. Our calculator can do this for you!
Ultrasound (Sonogram)
Early ultrasound provides very accurate estimation by measuring the baby's size, especially in first trimester.
Conception Date
If you know the exact conception date, add 38 weeks to estimate your due date.
How Accurate is My Due Date?
While an estimated due date provides a good guideline, it's important to remember that it's just an estimate.
- •Fewer than 4% of births occur on the exact due date
- •Approximately 60% of births occur within a week of the due date
- •Almost 90% occur within two weeks of the due date
Common Early Symptoms of Pregnancy
Pregnancy Tests: Confirming Your Suspicions
Pregnancy tests work by detecting human chorionic gonadotropin (hCG), a hormone produced only during pregnancy.
Clinical Blood or Urine Tests
Can detect pregnancy 6-8 days after fertilization. Highly accurate, detect smaller amounts of hCG earlier, but more expensive with longer wait times for results.
Home Pregnancy Tests
Widely available, convenient, and very accurate if used correctly. Typically effective from the day of your missed period or a few days after.
1. Medication Safety During Pregnancy
Taking certain medications during pregnancy can have lasting effects on the fetus. In the U.S., the FDA classifies drugs into categories (A, B, C, D, and X) based on their potential benefits versus fetal risks.
⚠️ Crucial Advice: Always consult your doctor before taking any medications (prescription, over-the-counter, or herbal supplements) during pregnancy or if planning to become pregnant.
2. Healthy Pregnancy Weight Gain
Weight gain is natural and necessary, supporting your baby's growth, placenta, and increased blood volume.

3. Exercise During Pregnancy: Staying Active Safely
Benefits of Exercise

4. Nutrition: Fueling Yourself and Your Baby
Proper nutrition during pregnancy is paramount for healthy baby development and your well-being. Your nutritional needs change during pregnancy, with increased energy requirements and specific micronutrient needs.
Key Nutrients
Helps decrease risk of neural tube defects
Essential for brain and retinal development
Personalized Advice
Many micronutrients are crucial for fetal development. Pregnant women should consult their doctors and/or a registered dietitian for the best nutritional plan for their specific needs.
Pregnancy is a unique and transformative experience. By understanding your timeline and focusing on healthy management practices, you can confidently prepare for your baby's arrival.
Always consult with your healthcare provider for personalized guidance every step of the way.
