Pregnancy calculator IVF

The long-awaited pregnancy and the emergence of two cherished strips on the test - this is one of the most moving and important moments in the life of every girl. This is especially true of those who have gone a long time, and resorted to the appearance of the child to the help of modern methods, including IVF.

As soon as the results of blood tests and pregnancy tests prove that conception has occurred, you must register at the antenatal clinic for further tracking the dynamics of development of the fetus. Women have questions regarding the calculation of pregnancy with IVF, a day considered as the moment of conception.

Calendar of pregnancy after IVF

Pregnancy Calendar was created primarily to track the development of the fetus, to understand what happens to the body of the future mother, as well as to know the supposed date of birth.

In normal pregnancy, the natural day of conception is considered the last day of menstruation. This so-called maternity period. In other methods countdown runs from the moment of conception or at all from the day of ovulation.

With the calculation of weeks at IVF things a little differently. To date, there is much debate about the calculation of the date of birth in vitro fertilization. In some methods, the count starts from the merger of sexual parental cells, and in others - the day replanting of a fertilized egg. That is why many ways created, counting the period of pregnancy with IVF.

It is important to understand that all calculators for setting a preliminary date of delivery are only relative. they usually expect two delivery date: the first baby at term gestation of 40 weeks and the second - with the possible reduction or increase in this period (from 38 to 42 weeks). It is always better to know the PRD at the doctor-gynecologist.

Methods of calculating the term of

Despite the abundance of calculators to calculate the exact date of birth is almost impossible. This is especially true of women with irregular menstrual cycles. Since IVF involves several stages, the question arises as to which of the moments of the procedure, it can be assumed that conception has occurred.

When calculating your date of birth, first of all, take into account the following factors:

• especially fruit size, detected during gynecological examination;
• day of the last menstrual period;
• the first movement of the child;
• hCG levels in the blood.

In addition, you can use a calculator pregnancy with IVF, which are freely available on the Internet. To calculate it is used as a date or time of the last monthly egg retrieval and embryo day replanting.

Obstetric

The first and one of the most common ways to calculate the date of delivery is an obstetric method. According to it, the countdown goes from the first day of the last cycle. In normal pregnancy and the menstrual cycle of 28-32 days duration of the day it is taken away 3 months and to this is added the number of 14 days.

For example, if the first day of the last menstrual period occurred on May 16, the pre-birth fall on March 2. Calculation after IVF has the same principle: the first day of the last cycle, it is necessary to add 9 months and 14 days.

Every woman's body is different all children develop at different rates, so the DA can be deflected in one direction or another.

On a similar methodology built most calculators to calculate gestational age. However, in cases of IVF is used less often because precisely known day of fertilization, and better use of more accurate methods of calculation.

Embryonic

The second type determination calculators DA based on the embryonic period. In this case, the first day is the moment of fertilization cells. If natural conception the parents can not say exactly when it merged germ cells. But in the case of IVF reproductive system can report the specific date of conception and the time of replanting the embryo in the mother's body.

Since the OB period countdown goes from the first day of the cycle, while embryonic - from the day of fertilization, then the period of gestation of the child may differ by about two weeks.

For gynecological examinations

After a successful IVF, as in natural conception, it is necessary to regularly visit an obstetrician-gynecologist. At each visit, your doctor may:

• determine the height of standing uterus;
• measure abdominal circumference;
• determine the mobility of the fetus.

In addition, your doctor may tell about the peculiarities of development of the baby at this stage, check the readiness of the genera (The last week), give advice on nutrition and receive additional vitamin complexes or natural funds.

Of course, a doctor can determine more accurate DRP, rather than an online calculator. After gynecologist examined the uterus and its neck, it can be assumed is now a woman is on a week.

The problem is that this method is informative only in the early weeks. Since starting in the second trimester uterine size and pace of development of the baby becoming an individual character.

Another method is fairly informative ultrasound. Ultrasound examination - a mandatory procedure for tracking pregnancy after IVF. Doctor should regularly receive information about the child's health, size and weight of the baby, and the development of all organs. After measuring the size of the coccyx-parietal (the first trimester), biparietal diameter, the length of the thighs, abdomen circumference, the program calculates the date of birth after IVF.

This method is popular in all trimesters of pregnancy. After receiving the ultrasound data doctor comprehensively evaluates the results of using a desktop calculator date of birth, date of inspection and the first stirring.

Calculating the date of birth IVF by ultrasound is the most accurate.

Often there are cases when the child's size does not correspond to the term of pregnancy. Such minor deviations are not of pathology and only represent the individual characteristics of the organism.

On the first fetal movements

Less informative, but the easiest way - this assumption is the term for the first movements of the baby. Each pregnancy is individually and then, at what period the expectant mother feels her child is dependent on many factors. But usually, you can track the traffic already on the 19-20 week.

This method is used only for self-assumption of the DA in the home. It's not the doctors, gynecologists and obstetricians apply. The method was applied to implementation in obstetric practice ultrasound.

Also you can use at your leisure and a calculator for calculating the duration of pregnancy, which are freely available on the Internet. Them there is a large variety of all calculators are based on different techniques: some consider the first day of the last menstrual period, and the other on the date of ovulation.

Calculator PRD after IVF

In vitro fertilization of sperm fusion with the egg is usually performed after 2-6 hours of collection of the follicular material. After 3-5 days of replanting carried in the womb and after about 2-4 days implantation occurs. If we compare this process with the natural cycle of a woman, then implantation occurs 5-8 days after ovulation.

Due Date Calculator can calculate both fetal and obstetric gestational age. In the first case it is necessary to count from the time of the selection of eggs, and in the second - to add to this day for another two weeks.

You can also use ready-made calculators. They must specify two parameters:

• the exact date of the transfer of the fertilized egg into the uterus;
• stage of embryo development with the transplant (its "age", which is calculated in days).

After this you should press the "Calculate" button, and the calculator will give the expected date of birth after IVF.

different situations, which are able to bring both, and, conversely, to defer the date of birth of the child may occur during gestation.

None of the above methods or calculators can not give a guarantee that this number is the date of birth. All calculators, techniques and methods of computation are only relative. Much depends on the mother's body, the length of the menstrual cycle and the individual characteristics of baby's development.

When issuing the hospital antenatal sheet is usually based on ultrasound data and the first day of the last menstrual period at short protocol. When long protocol based on the ultrasonic method.
