IVF Pregnancy Calculator Essential for Predicting Due Date

IVF abbreviates In Vitro Fertilization. It is a medical technique or treatment used for conception in sub-fertile couples. If the couple is unable to conceive after regular, un-protected sexual intercourse, medical practitioner investigates the problem. IVF is used when the sperm cannot reach the egg of female partner and fertilize it. Factors can be multiple ranging from woman to man medical problems which is not the scope of this article.

IVF Calculator is a bit different from the calculators used for estimating due dates through natural conception. This is due to the fact that in IVF Calculators due date is known and therefore prediction is more precise.

Fundamentals for Due Date

Rational behind calculation of due date for delivery is based on average gestational age at birth (the time since women has conceived) which is around 40 weeks from women’s last menstrual period. However, this is not necessary that your baby will be delivered on the exact date your doctor has estimated. There are natural variations in due dates and only about 10% mothers deliver their baby at the due dates estimated. Normal gestations period is between 37 weeks to 42 weeks according to medicine.

IVF Due Date Calculators

IVF due date calculations are more precise then natural conception due to multiple factors. IVF Calculators have the ability to calculate your date depending on your certainty over any of these:

  • First day of the last menses.
  • Day of ovulation.
  • Egg retrieval day also known as insemination.
  • Date of the three-day transfer of embryo.
  • Date of the fifth-day transfer of embryo.

IVF Calculator

You can use IVF Connections’ IVF Calculator for determining due date from your IVF Cycle or your current pregnancy. This is through a calculator that is more detailed in information like due date for multiples, trimester dates and prenatal testing fates. The calculator predicts the due date after the fertilized embryo (in test tube) is implanted in to the uterus of mother known as intrauterine insemination.

Note:

In Vitro Fertilization warrants physicians concerns for the due date. This is because with IVF there are increased chances of multiple pregnancies. In multiple pregnancies due date changes contrary to normal due dates in single pregnancies.

On average, due date for twins is 3 weeks before single pregnancies around 37 weeks of gestation, due dates for triplets is around 33 weeks of gestation and quadruplets are born around 31 weeks of gestation. There is also a raised concern of complications with IVF pregnancies like preterm labour i.e. labour before expected time.

Important Consideration on IVF

Couples having fertility problems have better chances through IVF. However majority get pregnant within 3 cycles of IVF. So it’s better to have three cycles of IVF before seeking other treatments

How Will I Know that IVF was Successful?

For this you will have to wait for around 2 weeks after the embryo transfer/insemination. The confirmation is done by checking the levels of hormones in your body using a blood or urine test.
