Frequently Asked Questions
How accurate is the due date calculator?▾
Due date calculations are estimates — only about 5% of babies arrive on the exact due date. The calculation is most accurate for women with regular 28-day cycles. First-trimester ultrasound dating (weeks 8-12) is considered the gold standard, accurate within ±5-7 days.
When should I start using the contraction timer?▾
Start timing contractions when they become regular and uncomfortable — not just Braxton Hicks tightening. The 5-1-1 rule (5 minutes apart, lasting 1 minute each, for 1 hour) indicates it is time to head to the hospital. Our Contraction Timer helps you track the pattern.
