Due Date Calculator
About Our Smart Due Date Calculator
Our smart calculator provides instant results and leverages AI to offer personalized insights.
Smart AI Pregnancy Calculator
"How many weeks am I?" It's the most common question for expecting parents. Our AI Pregnancy Calculator does more than count days. It synchronizes your LMP, Ultrasound, or IVF dates to tell you exactly where you are in your journey and what's happening with your baby right now.
Why Use AI Tracking?
Pregnancy math is confusing (40 weeks vs. 9 months). Our AI engine adjusts for your specific cycle length or embryo transfer date to resolve discrepancies, giving you a "Medical Week" calculation that matches your doctor's charts.
What You'll Discover
- Precise Dating: Your exact gestation in Weeks + Days.
- Development: Is your baby a poppy seed or a pumpkin?
- Timeline: Countdown to your next trimester.
Tracking Your Pregnancy: Week by Week
Pregnancy is officially measured in weeks, starting from the first day of your last period, not the day of conception. Our AI Pregnancy Calculator helps you translate these medical dates into real-life milestones.
The AI Accuracy Difference
Why do calculators give different results? Because biology isn't a straight line. Our AI Analysis considers:
- Cycle Variations: If your cycle is 32 days, you are technically "less pregnant" than someone with a 28-day cycle. We adjust for this.
- IVF Precision: For IVF moms, we calculate "Embryo Age" + 2 weeks for 100% accuracy.
- Ultrasound Corrections: We help you understand why your "Scan Date" might overrule your "Period Date."
The "40 Weeks" Myth
Did you know you aren't actually pregnant during "Week 1" and "Week 2"?
Weeks 1-2
Your body is preparing for ovulation. You haven't conceived yet, but medical dating counts this as the start.
Week 3
Fertilization happens. Sperm meets egg.
Week 4
Implantation. This is often when you miss your period and get a positive test.

Your Pregnancy Checklist
First Trimester (Wk 1-13)
- Start taking Prenatal Vitamins (Folic Acid).
- Schedule your first dating ultrasound (Week 8-10).
- Research NIPT screenings (Week 10+).

The "Safety Zone"
Pregnancy is counted as 280 days. However, a baby is considered "Full Term" anywhere from 39 weeks to 40 weeks and 6 days. "Early Term" is 37 weeks. Our calculator gives you the 40-week target, but be prepared for anything within the 5-week birth window!
