Understanding Pregnancy Calculations
Gestational Age Calculation
Gestational age is calculated from the first day of your last menstrual period (LMP), not from conception. This standardized method is used worldwide and aligns with medical dating conventions.
Why Different Methods?
- •LMP: Most commonly used, easy to remember
- •Conception: More accurate for irregular cycles
- •Ultrasound: Most accurate, especially early pregnancy
Pregnancy Trimesters
First Trimester (1-12 weeks)
Organ development, morning sickness common
Second Trimester (13-28 weeks)
Often called the "golden period", energy returns
Third Trimester (29-40 weeks)
Rapid growth, preparation for birth
Antenatal Care Importance
Regular antenatal care is crucial for monitoring both maternal and fetal health throughout pregnancy. This includes routine checkups, screening tests, and educational support.
