PregCalc is a web-based pregnancy calculation and tracking platform offering medically referenced tools to estimate due dates, gestational age, ovulation cycles and fetal development milestones. The software serves expectant parents, individuals planning conception and those seeking educational resources about pregnancy progression from pre-conception through postpartum stages. The platform aligns with clinical reference standards established by the American College of Obstetricians and Gynecologists and the World Health Organization and undergoes review by maternal health and pregnancy education specialists. The calculators and content are intended for informational purposes and are not substitutes for professional medical advice.

The suite encompasses over fifteen specialized calculators and tracking tools that support different phases of the reproductive and pregnancy journey. Core functionality includes a due date calculator that estimates delivery timing based on the first day of the last menstrual period or conception date inputs, a gestational age calculator that determines pregnancy duration in weeks and days, and an ovulation tracker that identifies fertile windows within the menstrual cycle. Additional tools include an assisted reproduction due date calculator, a conception date estimator, a pregnancy weight gain calculator, a fetal movement counter, a contraction timer, and fetal weight estimation functionality. A week by week guide describes developmental milestones and maternal changes throughout each trimester. Separate trimester guides organize information by stage, and supplemental resources include a gender predictor based on folklore theories, hospital preparation checklists, newborn growth percentile calculators, feeding trackers and postpartum development monitoring tools.

The platform operates as a standalone web application accessible via standard browsers on desktop computers, smartphone devices and tablets, with a responsive design that adapts to various screen sizes. There are no third-party integrations with electronic health record systems or other medical software applications. All calculations execute client-side within the user’s browser to maintain a privacy-focused architecture that neither stores nor transmits personal data. The platform provides content exclusively in English and operates on an open access model without subscription requirements or payment processing.

Methodology documentation indicates that the calculators utilize widely accepted medical formulas and reference guidelines for educational use only. The content and tools adhere to established clinical reference standards without detailing specific algorithmic implementations or proprietary validation processes. All resources are provided for informational purposes and are not intended as a substitute for professional medical advice or diagnosis.
