Medical Advice Disclaimer
The content on this website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. It is designed to provide general estimates and educational information about pregnancy milestones based on widely accepted obstetric formulas. Every pregnancy is unique, and individual factors such as cycle regularity, health conditions, multiple gestations, and genetic factors can significantly affect the accuracy of these estimates.
Always consult with a qualified healthcare provider for medical advice and before making any decisions related to your pregnancy. Do not disregard professional medical advice or delay in seeking it because of something you have read or calculated on this website. If you think you may have a medical emergency, call your doctor or emergency services immediately. Pregnancy Due Calculator by Conception does not recommend or endorse any specific tests, physicians, products, procedures, opinions, or other information that may be mentioned on the website.
Accuracy of Calculations
Our pregnancy calculators use standard obstetric formulas, including Naegele's rule for due date estimation (LMP + 280 days), the conception date method (conception + 266 days), and the IVF transfer method. While these formulas are widely used by healthcare professionals, they provide estimates rather than exact dates. The actual delivery date can vary significantly from the estimated due date, with only about 5 percent of babies born on their exact due date.
The accuracy of these calculations depends on the accuracy of the dates you provide and the regularity of your menstrual cycle. If you have irregular periods, polycystic ovary syndrome (PCOS), or other conditions affecting your cycle, the estimates may be less accurate. Ultrasound dating performed by your healthcare provider is generally more accurate than calendar-based calculations, especially in the first trimester. Our calculators should be used as a helpful reference point rather than a definitive prediction.
Not a Substitute for Professional Care
Our calculators are designed to complement, not replace, the care provided by your healthcare team. Prenatal care involves much more than calculating a due date, including monitoring fetal development, screening for genetic conditions, managing maternal health conditions, and preparing for delivery. Regular prenatal visits allow your healthcare provider to track your pregnancy progress using clinical methods such as ultrasound measurements, fundal height assessment, and fetal heart rate monitoring.
If our calculators provide a result that differs from what your healthcare provider has told you, trust your provider's assessment. Healthcare providers use multiple methods to determine your due date and pregnancy progress, and clinical evaluation is always more reliable than any online calculator. Our tools are best used for general information and to help you understand the principles behind pregnancy dating.
Emergency Situations
If you experience any emergency during your pregnancy, including severe abdominal pain, heavy bleeding, signs of preterm labor, decreased fetal movement, severe headache, vision changes, or any other concerning symptoms, contact your healthcare provider or emergency services immediately. Do not rely on this website or any online resource for emergency medical care. Time is critical in pregnancy emergencies, and prompt medical attention can be lifesaving for both mother and baby.
