Our Pregnancy Due Date & Milestone Tracker helps expecting parents plan ahead with confidence. Simply enter your last menstrual period (LMP) or conception date, and the calculator instantly estimates your due date based on the standard 40-week pregnancy timeline. Beyond just a date, you'll receive a detailed week-by-week breakdown of your baby's development — from the first heartbeat to full-term growth — covering key physical milestones, organ development, and what changes to expect in your body each week. Whether you're in your first trimester or counting down the final weeks, this tool keeps you informed and prepared every step of the journey.
