Calculating Ivf Due Dates: What To Expect During Your Treatment
A due date calculator, or pregnancy calculator, is an Internet-based tool used to find your due date (EDD).
These numbers are based on the average length of pregnancy, which is 40 weeks or 280 days, although a healthy, developing pregnancy lasts 37 to 42 weeks.
There are many free pregnancy due date calculators available online on pregnancy and women’s health oriented portals. In addition to the expected due date, these calculators often mention the baby’s weight or size at this stage of pregnancy.
There are three main ways to arrive at an estimated due date. They include the following:

This involves adding 40 weeks or 280 days to the first day of the last menstrual period (LMP). This method is most accurate for women with a normal 28-day menstrual cycle with ovulation on day 14. It should be noted that women are not pregnant in the first two weeks of pregnancy.
This includes counting 38 weeks or 266 days from the day the woman was born. For this method to be correct, women must observe ovulation because pregnancy can occur within 24 hours of ovulation. Therefore, most women find it easier to remember their LMP than their ovulation.
The so-called dating scan, ultrasound in the first trimester is a more accurate way to establish the gestational age of the child and the date of conception, especially for women who do not know their LMP. They have irregular periods and irregular ovulation. , or suspected pregnancy complications.
From the fifth week of pregnancy, the first structures of the developing fetus can be observed using transabdominal or transabdominal ultrasound. When assessing fetal development, especially fetal length (CRL), accurate gestational age is required to calculate fetal length.

First trimester ultrasound has an error of 5-7 days as it predicts the most accurate due date; However, its accuracy decreases over time.
Therefore, the last date of the first pregnancy calculated from the last menstrual period of the woman can be adjusted based on the ultrasound results of the first trimester. However, the second and third ultrasounds in the third trimester are usually not considered for determining the date of conception.
The date of pregnancy is one of the first and most important measurements taken during the first phase of pregnancy. Once a woman has confirmed that she is expecting, the expected due date can be found using a due date calculator or directly by adding 40 weeks to the first day of the woman’s last period. However, this method has its own limitations as it relates to women with a cycle of 28 days and normal ovulation on day 14. Mothers who want to get pregnant can add 38 weeks to their due date and calculate the due date of their pregnancy as possible. They track their cycles using fertility charts or ovulation trackers. However, the most accurate estimate of the period is ultrasound, which can measure the growth of the fetus and establish the pregnancy. However, for the ultrasound to be accurate, it should be done in the first trimester because its accuracy decreases as the pregnancy progresses. Your due date helps your doctor monitor your baby’s growth and development. They will use your due date to ensure that you and your baby are checked and screened at the appropriate stage of your pregnancy.

Calculating Your Ivf Due Date
Full term pregnancy is 280 days or about 40 weeks. (This is about 9.2 months, but includes the time before you got pregnant.)
Calculating your expected due date involves some math — and it’s a little tricky. There are several different methods you can use:
Used since the 1800s, this is the most common way to calculate due dates: Start with the date your last period started. Add 280 days. To do this, you can directly count 40 weeks in the calendar.
Or starting from the date your last period started. Minus 3 calendar months. Add 1 year and 1 week. This should give you the same date as above. Here is another way to get there.

For example, if your last period is June 1, subtract three months, then add one year, then add one week, and you will get March 8 of the next year.
Conception usually occurs within 12-24 hours of ovulation. So, if you are tracking it, use the ovulation date to make the prediction a little more accurate.
Calculating the due date for in vitro fertilization (IVF) is more accurate than some other methods because the calculation is based on a known transfer date.
Your doctor will do an ultrasound at the beginning of your pregnancy, around the end of the 13th week.
