Understanding Due Dates
A due date is an estimate of when your baby will be born, calculated as 280 days (40 weeks) from the first day of your last menstrual period. Only about 5% of babies are born on their exact due date.
Key Facts About Due Dates:
- Full Term: Babies born between 37-42 weeks are considered full term
- Natural Variation: Most babies are born within 2 weeks of their due date
- First Pregnancies: Often go past the due date by a few days
- Ultrasound Dating: Most accurate when done in the first trimester
Pregnancy Trimesters:
- First Trimester: Weeks 1-12 (organ development, morning sickness)
- Second Trimester: Weeks 13-27 (often called the "golden period")
- Third Trimester: Weeks 28-40 (rapid growth, preparation for birth)
