General description
The tool calculates estimated delivery date (EDD) based on the date of the last menstrual period, the date of conception or the date of embryo transfer. Based on the EDD, dates for each week of pregnancy are calculated as well as date ranges for appointments during pregnancy. Suggested weight gain during pregnancy is calculated based on the pregnant woman’s BMI. Fetal growth charts are the WHO international fetal growth charts.

The tool was developed in cooperation with asist. prof. Nataša Tul Mandić, MD, PhD, Division of gynaecology and obstetrics, University medical center Ljubljana.
Last menstrual period (LMP)
EDD = LMP + 280 days
Gestational age = Current date - LMP
Ultrasound date
EDD = Due date by ultrasound
Gestational age = Current date - (EDD - 280 days)
Conception date
EDD = Current date + 266 days
Gestational age = Current date - Conception date + 14 days
Embryo transfer
EDD = Transfer date + 266 days - (3 of 5 depends on user input)
Gestational age = Current date - Transfer date + 17 or 19 days
