IVF Due Date Calculator
The process of calculating your upcoming IVF due date is more precise than it is for your natural conception delivery date. The exactness of the embryo transfer is firmly known, thereby allowing you to determine an accurate due date. An automatic IVF due date calculator, courtesy of Kofinas Fertility Institute can be utilized. However, the basics of how to calculate your upcoming IVF due date can be just as easily understood by reading the following how to advice from Kofinas.
The Basics 
The average gestational age for a pregnancy is approximately 40 weeks – calculated from the woman’s last menstrual period. This is merely a basic estimated period of time given that healthy babies can be birthed at any time within 30 days short of the typical 40 week period. Typical gestation for a full-term baby is between 37 and 42 weeks – during which the baby may be delivered. Because the IVF due date calculator date is merely an estimated date – not a precise date – only 10 percent of women actually give birth on the day that is calculated per their IVF due date.
The Process of Calculating Your Upcoming IVF Due Date
You can calculate your upcoming IVF due date using any of these dates:
- The first day of your last menstrual period.
- The day of ovulation or egg retrieval procedure.
- The procedure day of inserting the embryo(s) into your uterus – the 3-day embryo transfer – or the 5-day embryo transfer.
An example of how an IVF due date calculator works is as follows:
May 1st = day of 3-day embryo(s) transfer into your uterus
June 1st = day you are calculating your upcoming IVF due date (gestational age is approximately 6 weeks)
January 19th = your upcoming IVF due date
Use the Kofinas trimester calculator and the Kofinas prenatal testing calculato for an automatic calculator that provides more detailed information such as your upcoming trimester dates or prenatal testing dates.
IVF Due Date Calculator for Multiple Births
Multiple pregnancies achieved through the IVF procedure may produce special considerations concerning your upcoming IVF due date. Because multiple pregnancies are very commonly produced using the IVF procedure, you should be aware of the following typical gestational periods should you become pregnant with more than one baby:
- Twins = 37 weeks
- Triplets = 33 weeks
- Quadruplets = 31 weeks
Two Week Waiting Period 
After your IVF procedure – the date of embryo(s) insertion into your uterus – you will wait for approximately 2 weeks for your pregnancy to be confirmed by way of a urine or blood test by your doctor. Kofinas Fertility Institute provides the compassionate emotional comfort and care you require during this agonizing 2 week waiting period.
