Fresh Vs Frozen Embryo Transfers
If youre going through IVF, heres what you might need to know about the difference between fresh and frozen embryo transfers. As you can probably surmise, one transfer involves freshly created embryos and the other involves embryos that were created at some time in the past and then frozen and stored.
Typically, a fresh embryo transfer occurs three or five days after egg retrieval for fertilization, according to the Society for Assisted Reproductive Technology . Typically, retrieved eggs are fertilized the day of retrieval, unless they are being harvested for freezing. By contrast, a frozen embryo could be frozen for months, or even years, before being thawed out and then transferred into the uterus. Frozen embryo transfers are very common, according to SART, with some people choosing to use frozen embryos left over from a previous cycle.
One thing you wont need to worry about is whether or not your estimated due date will be affected by whether your embryo was freshly created or spent some time in the freezer. The due date should be the same whether you are transferring a fresh or a frozen embryo, Dr. Murrain says.
Due Date Based On The Last Menstruation
When using this method, the due date is calculated by adding 280 days to the 1st day of your last menstruation. Note that this assumption is for a regular 28-day cycle, and that menstruation and ovulation are considered the first two weeks of pregnancy. The following rules are a modification of this calculation to get more precise results.
Since this method is influenced by the regularity of your menstruation, it cannot be 100% accurate. It also makes sense to track your menstrual cycle so you dont have to remember the exact date of your last period.

Example Results From An Ivf Due Date Calculator
To give you a better picture of how an IVF due date calculator usually works, here are two different sample scenarios. In each of these scenarios, the women conceived in different ways, but the timing of each conception is very close. Notice how the due date is different based on similar information. But every patient is different, so the due date of IVF given are approximate. The date on this IVF due date calculator is not intended to be a substitute for professional medical diagnosis or advice.

How To Use Ivf Due Date Calculator
You can choose any IVF due date calculator that you want, and many are available online to use. Your fertility specialist may also use one or refer you to one. An IVF due date calculator typically only requires one input. To use most calculators, determine the start date, based on the information above or what the calculator says to do.
While using the pregnancy calculator is simple, you have to pay attention to which date to use for frozen embryo or blastocyst transfers, IVF, ICSI, or other methods of conception.
The advantage of the free online IVF due date calculator is that you can also easily correct mistakes if you enter the wrong date, or choose the wrong start date for your specific situation.
How To Calculate In Weeks
To calculate how many weeks you are, start by taking note of the first day of your last period on a calendar, or your LMD . Every 7 days from that first day counts as 1 week in your pregnancy.
For example, if the first day of the last period was March 11 and you recently had a positive pregnancy test, your first day of pregnancy is March 11 . If March 11 was day 1, then March 18 will mark week 1 of your pregnancy. April 16, for example is calculated as 1 week and 1 day of your pregnancy, and you will have been in your second month.
Calculation is done this way because the exact fertilization day is difficult to determine. Sperm cells can survive in the womans body for up to 7 days, and can fertilize the egg and initiate the pregnancy on any of these days.

Why Pregnancy Calculators Can Only Estimate
There are only few reasons behind why the calculators for pregnancy only estimate pregnancy schedules:
- No doubt, LMP calculation entirely depends on a regular 28-day menstrual cycle, with ovulation taking place 14 days into the cycle. Thus, divergence exist as this does not account for menstrual cycle length irregularities and even variability in ovulation timing
- Remember that the development of human life is not already programmed at all, same case of their birth. Every women have variations in their pregnancy week by week, even the exact time at which baby develop is variable. Thus, the pregnancy week by week calculator only estimates your pregnancy weeks highlights
- There are certain complications due to which the delivery timeline can be changed. However, the time comes when labor is induced to prevent harm to expecting moms or their baby. This is the parameter that can significantly alter the timeline of your little ones arrival

Conception Calculator Based On Due Date
So, what day did I conceive? There are two ways to use our conception calendar calculator.
The first way is to provide the birth due date. When you visit the doctor they will most likely perform an ultrasound. Although the doctor can see the baby from the 5-6th week of pregnancy, the best time to go for the first sonography is between week 8 and 12.
Based on the characteristics of the image and the results of your blood test, the due date and week of pregnancy can be determined. Remember that those dates, as well as conception calendar, are only an estimation and may change during the next visit.
Pregnancy typically lasts around 40 weeks . That is 266 days from the conception date. If a baby is born before week 37, its called a premature birth. But dont worry if the due date changes or you go in labor on a different date only 4% of babies are born on their due date and 80% are born either two weeks before and after the date.
Lets go back to the question: what day did I conceive? In our conception calculator, we subtract 266 days from the estimated due date and get the most probable day of conception:
due date 266 = conception date

How Accurate Is Pregnancy Due Date Calculation
Pregnancy due date calculation is a rough estimate of the likely date at which the baby can be born. Only 5% of babies are born exactly on the due date, while all others are born a few days before or after it. The inaccuracy of LMP date and the variation in the exact date of fertilisation are factors influencing the difference in the actual delivery date and the expected due date.
The anxiety around the due date is a very normal feeling among pregnant women. The due date that the doctor provides usually gives an approximate time frame for all the preparations towards delivering the baby. Weeks, months or trimesters are often used to quantify the stage of pregnancy and you can choose any method that you find convenient.

Determining If Labor Is Premature
Babies who are born too early are at risk for numerous health problems. There are steps we can take to slow or halt preterm labor. With that said, there are also risks to the medications used to stop preterm labor, both to the mother and the baby.
You and your doctor have to decide together when the risks of allowing labor to continue to outweigh the risks of intervention. This is partially determined by knowing which week of pregnancy you are in.
There are also risks to the baby and mother if a pregnancy goes on for too long. Post-term pregnancy is when birth does not occur by week 42 . If this happens, your midwife or doctor may decide to induce labor.
How To Calculate Pregnancy Weeks After Ivf
In calculating pregnancy after IVF, its clear on which day fertilization occurs, unlike normal pregnancy. Since you will follow your natural menstrual cycle in IVF procedures, the date of embryo entry into your uterus coincides two weeks after the first day of your last menstrual period. You can calculate the probable date of birth by adding 266 days to the day of the embryo entering your womb. If the B-HCG test is positive 12 days after the embryo is placed, that is, if pregnancy has occurred, the gestational week is considered to be four weeks.

Can The Pregnancy Conception Calculator Be Wrong
Yes, of course. So, when does conception happen? There is no possibility being 100 % sure about it. You may be a little bit more certain if you track your cycle and have it perfectly regular. But even ultrasounds and blood tests arent faultless. Remember, that your fertile window begins up to 5 days before ovulation and ends one day after it. So, although your conception date is, e.g., 11 July 2019, the intercourse that caused the pregnancy may have occurred as early as 6 July. However, with our conception calendar calculator, you can make an estimated guess!

First Day Of Last Period
Most pregnancies last around 40 weeks , so typically the best way to estimate your due date is to count 40 weeks, or 280 days, from the first day of your last menstrual period .
Another way to do it is to subtract three months from the first day of your last period and add seven days. So if your last period started on April 11, youd count back three months to January 11 and then add seven days, which means your due date would be January 18.
This is how your doctor will estimate your due date and its a pretty solid target. But remember: Its just as normal to deliver a week or two before or after.

What Are The Different Ways To Estimate The Due Date Of A Pregnancy
The following ways help calculate how many weeks pregnant a woman is and the estimated due date.
Calculating by using the date of the last menstrual period
This is one of the most common, simple and most accurate ways to figure out how many weeks pregnant a woman is and estimate the approximate due date. The way to calculate the due date is to take the first date of the last normal period and add 280 days , which is the typical length of a normal pregnancy. The period that is to be tracked should be typical of a womans menstrual cycle. This means it should be the same number of days as a usual period, the same amount of bleeding and the same amount of discomfort. Thats because sometimes a woman may bleed after shes pregnant, but that bleeding is different from a normal period.
- The formula for calculating how many weeks pregnant a woman is the number of days since the first day of her last menstrual period divided by seven. So, the number of days since the start of LMP divided by seven equals the number of weeks pregnant
- The formula to calculate how many months pregnant a woman is the number of days since the first day of a womans last menstrual period divided by 30. This means the number of days since the start of LMP divided by 30 equals the number of months pregnant.
