Pregnancy calendar

Being pregnant is a thrilling and occasionally daunting experience. There are numerous milestones to enjoy as your baby grows and your body changes. Being aware of weekly events can make you feel more unified and ready for the upcoming months.

A pregnancy calendar can be a helpful resource to help you navigate these unique times. It provides weekly updates on your pregnancy, including information on your body’s changes, the development of your unborn child, and what to anticipate at each stage.

This calendar will assist you in staying informed throughout your pregnancy, whether it’s your first time or you’ve done it before, helping to reduce some of the uncertainty that comes with this special journey. Let’s examine each stage so you can prepare for and accept the changes.

What is the difficulty?

At first glance, there is nothing complicated in counting the pregnancy period, and many women can even confidently say when exactly the sexual intercourse took place, which led to the conception of the baby. But this information has nothing to do with the correct calculation, besides, it can confuse the expectant mother. As a result, the woman will convincingly prove to the attending physician that he is mistaken, that he calculates her period incorrectly, many questions will arise. So that there are no discrepancies, there is a obstetric system for calculating pregnancy, it is on it that the compilation of the calendar is based. It should be noted that all the analyzes that are recommended for pregnant women with reference to the deadline, all examinations and screening, as well as the calculation of the date for which the estimated day of childbirth is, are made only in obstetric weeks, and therefore, from the very beginning, it is worth trying to master this technique, so that there are no difficulties and questions.

There are two ways to create a pregnancy calendar: with an interactive calculator or by hand. The obstetric method is the foundation for both approaches when calculating gestational age. Once the current period has been established, you can proceed to determine which leg of the nine-month journey you are in.

How to count?

The menstrual cycle in women is different. For one it lasts 26 days, for another – 35 days, and this can be considered an individual feature over which medicine has no power. The obstetric method is based on the understanding of one simple truth – pregnancy cannot occur on any day of the cycle except ovulation. It is during the period of the release of a mature oocyte from the follicle on the surface of the ovary, where the sex cell matured in the first half of the cycle, that fertilization occurs. Before this, it is impossible, since two sex cells are needed for conception – male and female. After release, the oocyte lives from 24 to 36 hours, and if fertilization does not occur during this time, the female sex cell dies, and conception in the current cycle becomes impossible.

• Ovulation occurred, and the sperm were already waiting for the female cell in the genital tract (if unprotected intercourse was no later than 3-4 days before ovulation).
• Ovulation occurred, and within a day and a half the sperm arrived in the fallopian tube after ejaculation as a result of unprotected sexual intercourse.

That being said, the process of fusing the parents’ germ cells—which creates a new life—only takes place during ovulation, neither earlier nor later.

This drastically reduces the chances of conception but also makes it easier to pinpoint the exact time of pregnancy. It is assumed by default that it occurred during ovulation. You only need to deduct 14 from the cycle’s duration to find the ovulation period.

However, obstetricians avoid counting pregnancies based on ovulation because this can result in serious mistakes. It is a fact that ovulation can occur both sooner and later than anticipated. The fact of ovulation displacement cannot be proven in any way if a woman does not specifically track it, does not record every sexual activity throughout the cycle. For this reason, the obstetric approach is employed, whereby the pregnancy is measured starting on the first day of menstruation—the last day prior to the delay.

Crucial! Since the cycle starts on the first day of menstrual bleeding, you should use the first day of the last menstruation as your basis rather than the last day of the menstrual cycle.

Setting the gestational age to the exact day is not possible with the obstetric calculation, but it is not necessary to do so in order to create a pregnancy calendar.

Given that the embryo did not yet exist, it may seem odd that the first day of menstruation coincides with the beginning of a pregnancy. There is no mistaking, I promise: the obstetric period differs from the gestational period, which lasts for roughly two weeks from the time the mother’s and father’s genital cells merge on the day of ovulation.

Every time a pregnant woman sees a doctor, the conversation always starts with the date of the last menstruation. This makes it possible for a future mother and specialist to "Keep the watch."

Therefore, the first day of pregnancy is also the first day of the last menstrual cycle. Additionally, the countdown is carried out for weeks that are identical to the calendar. In terms of obstetric weeks, the average pregnancy lasts 40 weeks.

The anticipated birth date, if all your calculations are accurate, is at the conclusion of the 40th week.

It is necessary to discuss obstetric months and trimesters separately. Pregnancy is divided into three trimesters, each lasting three calendar months.

• The first trimester starts from the 1st week and ends with the 13th week inclusive;
• The second —from the 14th week to the 26th week;
• The third —from the 27th week until delivery.

It is easy to notice that a calendar month has more than four weeks in it simply by looking at it. However, since the obstetric month has exactly four weeks, just like the lunar month, your pregnancy will have ten months according to the obstetric calculation of the term and nine months according to the widely accepted calendar calculation.

You can use one of the obstetric formulas to find the delivery date.

• To the first day of the last menstruation, you need to add nine calendar months and another seven days.
• From the first day of the last menstruation, you can subtract three months and add seven days to the resulting value.
• You can simply add 280 days to the first day of your last period.

For all pregnant women, the date that results will be known as the beloved abbreviation EDD, or expected date of birth. Practically speaking, labor can start at any time between the 38th and 42nd week of pregnancy.

Let’s look at an example of creating your own calendar.

• A woman"s cycle lasts 28 days, menstruation – 4 days, the last menstruation began on January 1, 2019.
• Subtract 14 from 28, we get the 14th day of the cycle. This means that presumably ovulation occurred on January 14, and the embryonic period is counted from this day.
• To determine the gestational age, we count from January 1. We get that on the day of ovulation there were 2 weeks of pregnancy, and on the day of the onset of the delay – 4 obstetric weeks.
• To determine the due date, we use one of the above formulas and get that it is October 8, 2019.

You can easily determine the approximate date of the baby’s birth by purchasing a pre-made round obstetric calendar.

Pregnant women should not be without a pregnancy calendar, which offers an easy-to-use method of monitoring their unborn child’s growth every week. From early symptoms to important milestones, it helps parents understand what to expect at every stage of pregnancy, which makes it easier for them to plan ahead and take care of their health and well-being during this exciting time.

Interactive calendar

By relieving a pregnant woman of the need to conduct independent mathematical research, the online calculator lowers the risk of a common arithmetic error. The pregnancy period and the birthdate can be quickly and easily calculated with this free program in a matter of seconds. The obstetric techniques for figuring out the period mentioned above serve as the foundation for the computation.

In a unique form, you only need to enter one value: the date of the last menstrual period’s start, formatted day-month-year. As a result, a woman can see her expected date of conception, or EDD, and can almost instantly find out what stage of her cycle she is in with accuracy as high as one day or up to one week.

She also has the chance to learn what trimester she is in, what symptoms and sensations are normal at this point, and how the baby is growing.

Many services offer a comprehensive and precise list of required tests and examinations by week, month, and even day of pregnancy, along with gynecological recommendations for this time.

Because the female body starts methodically and gradually preparing for childbirth almost from the very beginning of pregnancy, using the service makes tracking physical changes very convenient. There will be thorough and detailed information provided for every week of pregnancy, which will aid in providing answers to many of the questions that expectant mothers, without exception, have for themselves.

The calendar’s weekly recommendations on nutrition, personal hygiene, intimate life, clothing, footwear, and lifestyle are particularly helpful. Expert consultations via the internet are offered by certain services.

On a tablet or smartphone, calculator apps are also available for download and installation. Based once more on the first day of your most recent menstrual cycle, this electronic assistant will perform the necessary computations, remind you every weekday when a new week begins, and provide recommendations and helpful advice specific to your menstrual cycle.

Online tools and calculators are available that not only offer medical data but also extra details about the closest pharmacies, baby shops, and hospitals. They can also be used to determine the future child’s zodiac sign and generate a personalized horoscope, which can be useful when deciding on a baby’s name.

The majority of services and applications display the baby’s image at various stages of pregnancy and offer fetometry data, allowing a woman to compare the baby’s actual size with the average after visiting the ultrasound room. As you are aware, one of the things that expectant mothers like to do most when they wait for their baby to arrive is this.

Other methods

The pregnancy period and the birthdate cannot be determined in any other way, however in questionable situations, there are methods to verify the pregnancy period. This is an ultrasound analysis. It’s important for you to know that obstetric terms and procedures are specifically tailored into the software that scanners have on board.

Every woman typically has her ultrasound term confirmed when she visits the ultrasound diagnostics office. This is accomplished by the diagnostic specialist entering the date of the last menstruation into the scanner program and comparing it with the baby’s size standards for the terms.

If the woman cannot recall the date of her last menstruation, it will be more difficult. This occurs with severe and persistent irregularities in the menstrual cycle, and in this instance, the term is established solely based on the ultrasound findings, cross-referenced with the fetometry table.

Since all embryos develop according to the laws of nature at nearly the same pace up until a certain point, after 9–10 obstetric weeks, the actions of the genetic program start to manifest, which is different for every baby, the earlier the ultrasound is performed, the higher the probability of getting an accurate result. One will be tiny and smaller than average; it will be smaller than usual, and the other will be larger than usual—like dad or grandfather—and will be larger than usual even in the womb.

Using a calendar to track your pregnancy is an easy yet powerful way to keep tabs on both your own health and the development of your unborn child. It assists you in keeping track of significant dates, from the first trimester to delivery, so you can be ready for every turn of this wonderful journey.

In addition to keeping track of your unborn child’s growth, using a pregnancy calendar helps you get ready for impending checkups and prenatal care. It’s a useful tool that can help to organize and de-stress the entire process.

In the end, adopting a pregnancy calendar can help the process go more easily and calmly. You can take greater confidence and peace of mind into this unique time by monitoring your progress and remaining informed.
