Where:
Explanation: This calculation provides an estimate of pregnancy duration in completed months, which is commonly used for tracking pregnancy progress.
Details: Accurate pregnancy dating is essential for monitoring fetal development, scheduling prenatal care, and determining estimated due date. Regular tracking helps ensure both maternal and fetal health throughout pregnancy.
Tips: Enter the first day of your last menstrual period and the current date (or any date you want to calculate for). The calculator will determine how many completed months pregnant you are at that point in time.
Q1: Why use 30.44 days per month?
A: 30.44 represents the average month length (365.25 days per year ÷ 12 months), providing a standardized calculation method.
Q2: How accurate is this calculation?
A: This provides a general estimate. For precise pregnancy dating, healthcare providers use ultrasound measurements and clinical assessment.
Q3: What if I don't know my exact LMP?
A: If unsure about LMP, consult with a healthcare provider who can estimate gestational age through ultrasound examination.
Q4: Does this account for different month lengths?
A: The calculation uses average month length. For clinical purposes, pregnancy is often tracked in weeks rather than months for greater precision.
Q5: When should I see a doctor for pregnancy confirmation?
A: Schedule an appointment with a healthcare provider as soon as you suspect pregnancy for proper confirmation and prenatal care guidance.
