The time between conception and delivery is known as the gestational period. The baby develops and grows during this time inside the mother's womb. From the start day of the woman's most recent menstrual cycle to the present day, it is counted in weeks. A typical pregnancy lasts between 38 and 42 weeks.
Gestational age is calculated from the last day of a woman's menstrual cycle and reflects the physical development of the fetus. It includes the embryonic stage (weeks 5-10) and the fetal stage (week 10 to delivery). Doctors may use ultrasounds or physical measurements to determine gestational age.
LMP (Last Menstrual Period) is the first day of your last menstrual period before becoming pregnant. It helps estimate the date of conception and the expected due date. The average menstrual cycle lasts 28 days, with ovulation around day 14.
Estimated Date of Delivery (EDD) is the expected date when a pregnant woman will give birth. It is calculated as 280 days (40 weeks) from the LMP. Accurate EDD is essential for proper prenatal care.
Crown Rump Length (CRL) is the measurement of the fetus from head to bottom. It is the most accurate estimate of gestational age during the early stages of pregnancy.
Biparietal Diameter (BPD) measures the distance between the parietal bones of the developing baby's skull. It helps determine gestational age and fetal weight.
In Vitro Fertilization (IVF) is a fertility treatment where eggs are fertilized by sperm in a lab and then implanted in the uterus. It is a successful assisted reproduction technique.
Gestational age is calculated from the first day of the last menstrual period, while fetal age starts from the date of conception. Fetal age is typically two weeks behind gestational age.
