About

Pregnancy Calculator is a free, ad-free tool designed to help expecting parents accurately calculate their due date using three methods: Last Menstrual Period (LMP), IVF retrieval date, or embryo transfer day. Unlike many online calculators, it supports both 3-day and 5-day embryo transfers, making it especially useful for those going through assisted reproductive treatments.

Built with simplicity and clarity in mind, Pregnancy Calculator provides a fast, mobile-friendly experience without the clutter of popups or unnecessary ads. Whether you’re early in your pregnancy or just starting your journey, it gives you instant access to your estimated due date, current pregnancy week, and trimester — all in one place.
