The Ultimate Pregnancy Countdown: From Bump to Baby

Congratulations, mama-to-be! Whether you're just seeing those two pink lines or already feeling tiny kicks, this guide will walk you through pregnancy like your best friend who's been there three times. Plus, don't forget to use our Pregnancy Due Date Calculator to mark your personal countdown!
When Will Your Baby Arrive? The Due Date Lowdown
Only 5% of babies arrive on their actual due date! Here's what really determines your big day:
- Last Period Method: Add 280 days (40 weeks) to the first day of your last period
- Ultrasound Dating: Most accurate in first trimester (measures baby's size)
- IVF/Assisted Pregnancy: Uses embryo transfer date
Pro Tip: Your "due month" is more realistic than a specific date! Most babies arrive between 37-42 weeks. Calculate your range here.
