Multi-function pregnancy calculator. Created by a board-certified ObGyn.

Calculate dates of pregnancy:
-Last menstrual period (LMP)
-Estimated date of conception
-Weeks gestational age (WGA)
-WGA obtained by ultrasound
-Dating by IVF Embryo transfer
-Calculate gestation by Crown-Rump length
-Estimated due date (EDC)
-“Time Machine” mode can calculate “How many weeks will patient be on xxxx date?” and “When will patient be xx weeks gestation?”

Features still present, but no longer supported:
-Store multiple patients for easy retrieval
-Adjust length of cycle and luteal phase
-Full Help pages
-Include extra notes in patient data

This app calculates exactly 280 days (40 weeks) from LMP to EDC, and accordingly for any date in between. Please note that the paper/plastic wheels used by obstetricians or ultrasound technicians are inherently inaccurate. Different pregnancy wheels may vary by as much as 3 or 4 days. Please keep this in mind when comparing the values obtained here to those given in clinics/hospitals.
