How the IVF Pregnancy Calculator Works

IVF (In Vitro Fertilization) treatment is advanced technology that the specialists have been working on refining for a long time. Due to the unavoidable level of uncertainty involved in this process, they were unsure of using this method of promoting the birth rates. But now the specialists have made it safer and effective as well in order to end up with successful results. The success rates of the treatment are growing with every passing day. Women who were afraid to go for it are now confidently taking advantage of this new solution to increase their chances of having a baby.

When the embryo starts developing in the womb after the IVF treatment, it then becomes possible to calculate the due date. A specific IVF pregnancy calculator can be used to calculate the due date as it gives different and more accurate results than the typical due date calculator for natural pregnancies. This difference occurs because the exact date of transferring the embryo is known to both the patient and medical team, as you must have had to come back into the office for them to be transferred.  The IVF calculator can surely be a lot of help for determining the exact date of the baby’s birth.

IVF Pregnancy CalculatorThe due date concept

The due dates are determined from the gestational period which can be up to 42 weeks maximum. The due date is the estimated date the baby will be born healthy. The gestation period usually varies from 37 weeks to 42 weeks and the baby may be born anytime between these ranges. TAs a reminder, due dates are only an estimate of the time at which the baby will be born. It is not fool proof or a promise carved into stone, as the actual ratio of women giving birth at the exact due date is only 10%.

The IVF due date calculations

The natural due dates, as well as the gestation period, are calculated with respect to the first day of the woman’s last menstrual period. Usually, after 14 days of the menstrual period, the conception and ovulation occur. The full gestation period will be  42 weeks if the last menstrual period was at June 1 This would leave us to believe that the baby would have probably been conceived around June 14, therefore making  the due date the first week of March.

The natural conception due date calculations are not as accurate as the IVF pregnancy calculator, simply because we know the fertilization and transfer dates.  . The ultrasound growth measurements are also used to get an idea about the due date.

The IVF pregnancy calculator

To know the right due date with the potential cycle of IVF, you can use the pregnancy calculator linked with IVF for the exact due date. Having a calculator that provides you with the exact dates is surely a blessing. The IVF pregnancy calculator is also used to calculate the due date after going through the IVF process and the IUI (intrauterine insemination) process.  [We’ll get into the whole IUI vs IVF discussion in another article!]

How is the due date calculated?

After the IVF treatment, or in other words after the transferring of the embryo, you would have to wait for at least two weeks to see if the embryo is growing and developing or not. After the two weeks of patience when the development starts then the due date can be determined. The pregnancy due date calculator IVF makes it easy to do.

The due date is actually calculated by adding in the 40 weeks to the first and last day of the menstrual cycle which is usually the 28-day cycle. The point to ponder here is that the ovulation and the menstrual period are considered as the first two weeks of the pregnancy. So when you deliver the baby right exactly on the due date then the baby becomes 38 weeks old instead of 40. In other words, the baby is 9 months and five days old instead of 10 months old.

Sorry, it is only an estimate! Pregnancy Due Date Calculator IVF
