Pregnancy Due Date Calculator 🤰
Calculate your estimated due date, gestational age, and view weekly milestones.
This calculator provides an estimate. Ultrasound is the most accurate method for due date confirmation, especially early in pregnancy. Always consult with your healthcare provider.
ℹ️ Pregnancy Calculator Info
LMP (Last Menstrual Period) is the first day of your last menstrual cycle. It is used to calculate gestational age and estimate your due date when the exact conception date is unknown.
EDD is calculated as 280 days (40 weeks) from the LMP. Actual delivery may vary by ±2 weeks, as only a small percentage of babies are born exactly on the predicted due date.
Pregnancy has three trimesters: • 1st Trimester: Weeks 1–12 • 2nd Trimester: Weeks 13–26 • 3rd Trimester: Weeks 27–40 Each stage includes important fetal growth and changes.
Gestational age measures how far along the pregnancy is, starting from LMP. It helps doctors track fetal growth, schedule scans, and plan medical care.
Conception usually occurs around 14 days after the LMP, during ovulation. The calculator estimates this date for better understanding of fetal development timelines.
Every pregnancy week has unique developments -- from heartbeat formation to brain growth, movement, and preparation for birth.
✔ Determine due date ✔ Know pregnancy week & trimester ✔ Track fetal milestones ✔ Prepare for scans ✔ Stay informed during pregnancy
This tool assumes a 28-day cycle. If your cycle is irregular, dates may vary. Consult your healthcare provider for personalized medical guidance.
The fetus develops rapidly: heartbeat at week 6, major organs by week 10, movement by week 18, and lung maturity closer to birth.
CRL (Crown-Rump Length) is the most precise measurement for early pregnancy dating. It is usually measured between weeks 7 and 13.
A balanced pregnancy diet requires nutrients like folate, iron, calcium, omega-3 (DHA), and proteins for healthy fetal growth.
Important tests include NT Scan, Anomaly Scan, glucose testing, blood work, and regular checkups to ensure healthy fetal development.
Changes like nausea, cravings, breast tenderness, or mood swings are common. Symptoms vary by trimester and person.
• Week 6: Heartbeat • Week 10: Organs formed • Week 20: Gender detection • Week 28: Active brain • Week 36: Final growth phase
The baby's brain develops millions of neural connections, especially from weeks 20–36. Baby begins responding to sound and light.
Healthy weight gain depends on BMI. Typically 10–14 kg is recommended, but may vary based on mother’s health and doctor’s advice.
Ultrasound scans check fetal heartbeat, growth, organ development, placenta position, and overall pregnancy health at different stages.
Common early signs include missed period, nausea, fatigue, increased urination, and mood changes. These vary for each individual.
