Frequently Asked Questions About Pregnancy Tools
How accurate are pregnancy due date calculations?
Due date calculations are estimates based on average pregnancy length (280 days from last menstrual period). Only about 5% of babies are born exactly on their due date, with most delivering within 2 weeks before or after.
Can I use these tools if I have irregular periods?
If you have irregular menstrual cycles, due date calculations based on your last menstrual period may be less accurate. Your healthcare provider may use ultrasound dating for more precise estimates.
Are the weight gain recommendations the same for everyone?
No, weight gain recommendations vary based on your pre-pregnancy BMI, whether you're carrying multiples, and individual health factors. Our calculator provides personalized recommendations.
Do you store my personal information?
No, we do not store any personal information entered into our calculators. All calculations are performed locally in your browser for privacy and security.
