IVF Pregnancy Calculator
Tsong Law Group
IVF Pregnancy Calculator is a free tool for intended parents, gestational carriers, and fertility professionals. It turns embryo transfer details into due dates and gestational weeks, helps you plan key milestones, and now includes a BMI calculator. IVF pregnancies are tracked two ways: gestational weeks, counted from the last menstrual cycle, and weeks post embryo transfer, counted from the transfer date. Converting between the two isn't always easy. Enter the transfer date and the age of the embryo, and the app does the math for you. In surrogacy contracts, both numbers can matter, such as the week a baby is considered premature or full term, and when certain contract benefits begin. IVF CALCULATOR • Calculate gestational age from embryo transfer details (day 3 to day 7 embryos) • Estimate a due date from IVF transfer timing • Work backward from an estimated due date • Find the date of a specific gestational week or week after transfer • Plan several milestone dates at once with the multi-date planner • Just for fun, see the baby's size compared with a fruit, week by week BMI CALCULATOR (NEW) • Calculate body mass index in pounds and feet/inches, or kilograms and centimeters • Many clinics require gestational carriers to have a BMI of 32 or less.
