Frequently Asked Questions
How accurate are these pregnancy calculators?
Our calculators provide estimates based on standard medical formulas. Accuracy depends on having regular menstrual cycles and knowing the exact dates of your last period. Due date predictions are typically accurate within a range of ±2 weeks.
Can I use these tools if I have irregular periods?
While you can use these tools with irregular periods, the results may be less accurate. For irregular cycles, ultrasound dating early in pregnancy provides the most accurate estimate of gestational age and due date.
