About Pregnancy Calculator Hub
Our Mission
Pregnancy Calculator Hub exists to give every expecting parent — and everyone trying to become one — free, accurate, and easy-to-understand tools for every stage of the journey. We believe that access to reliable pregnancy information should never depend on a subscription fee, a doctor's appointment, or wading through confusing medical jargon.
Our calculators are built on the same clinical formulas used by obstetricians and midwives worldwide, presented in a clear, friendly format that anyone can use from their phone or laptop in seconds.
What We Offer
Due Date Calculator
Calculate your estimated due date (EDD) using your last menstrual period (LMP) or IVF embryo transfer date. We apply Naegele's Rule with cycle-length adjustment — the same method endorsed by ACOG — and display your full trimester timeline and current gestational age.
Ovulation Calculator
Identify your fertile window and peak ovulation day based on your cycle length and last period. Our calculator highlights your six-day fertile window and provides a 3-month forecast so you can plan ahead.
Pregnancy Week-by-Week Tracker
Follow your baby's development from Week 4 through Week 42. Each weekly page covers fetal size and milestones, common pregnancy symptoms, nutrition tips, and what to expect at upcoming prenatal appointments — all sourced from peer-reviewed medical literature.
Baby Name Finder
Explore thousands of baby names with meanings, origins, and cultural context. Filter by popularity, origin, or starting letter to find the perfect name for your little one.
