Frequently Asked Questions
How accurate is the pregnancy calculator?
Our calculator provides estimates based on standard medical calculations. The most accurate method is using ultrasound data with gestational age. Due date calculations are typically accurate within 1-2 weeks for most pregnancies.
What's the difference between gestational age and conception age?
Gestational age is calculated from the first day of your last menstrual period and is used by healthcare providers. Conception age is the actual time since fertilization occurred, which is typically about 2 weeks less than gestational age.
How do I know which calculation method to use?
Use the method with the most accurate information you have. Ultrasound dating is most precise, followed by due date, then last menstrual period. If you know your exact conception date or had IVF, use those methods for the most accurate results.
Are the weight gain recommendations personalized?
Yes! Our weight gain recommendations are based on your pre-pregnancy BMI and follow Institute of Medicine guidelines. The recommendations are tailored to your specific body type and health status.
Can I use this calculator throughout my pregnancy?
Absolutely! The calculator provides updated recommendations as your pregnancy progresses. You can recalculate weekly to get updated trimester guidance, symptoms, and milestones.
