Who We Are
The Pregnancy Due Calculator by Conception was created to help expectant parents easily and accurately calculate their pregnancy milestones. We understand that pregnancy can be both exciting and overwhelming, and having access to reliable information and tools can make the journey smoother and more enjoyable. Our calculators use the same methods trusted by healthcare providers, including Naegele's rule for due date calculation and standard ovulation prediction algorithms, giving you confidence in the results you receive from our tools.
Our team is dedicated to providing the most accurate and up-to-date pregnancy information available. We regularly review and update our calculators and content to reflect the latest medical guidelines and research. Every formula used in our calculators has been verified against established obstetric standards, and we clearly explain the methodology behind each calculation so you can understand exactly how your results are determined. Transparency and accuracy are the cornerstones of our approach to pregnancy calculation tools.
We recognize that every pregnancy is unique, and while our tools provide valuable estimates based on standard medical formulas, they are not a substitute for professional medical advice. Always consult your healthcare provider for personalized guidance about your pregnancy, especially if you have irregular cycles, high-risk pregnancy factors, or other medical conditions that may affect the accuracy of standard calculations. Our tools are designed to complement, not replace, the care you receive from your medical team.

Our Story
The idea for Pregnancy Due Calculator by Conception was born from a simple observation: many expectant parents struggle to find reliable, easy-to-use tools for calculating their pregnancy milestones. While healthcare providers offer excellent guidance during appointments, parents often want quick answers between visits. Is my due date calculation correct? When did I likely conceive? When should I take a pregnancy test? These are questions that deserve accurate answers available at any time of day or night.
We built this website to bridge that gap, providing a comprehensive suite of pregnancy calculators that use the same formulas and methods recommended by obstetricians and gynecologists worldwide. Our due date calculator supports three different calculation methods, last menstrual period, conception date, and IVF transfer date, because we understand that the path to pregnancy varies for every family. Similarly, our ovulation calculator accounts for different cycle lengths, and our pregnancy test calculator considers the biology of implantation and hCG production.
Since our launch, we have helped millions of expectant parents navigate their pregnancy journeys with confidence. Our commitment to privacy means that none of the information you enter into our calculators is stored or transmitted, everything happens right in your browser. We believe that your personal health information should remain personal, and we have designed our entire platform with this principle at its core. Thank you for trusting us with this important part of your pregnancy journey.
