Pregnancy Calendars


A pregnancy calendar refers to a log kept by the mother in order to actively monitor changes taking place with her body and the baby. The calendar spans over the total of 40 weeks of pregnancy. These 40 weeks are divided into 3 semesters: The first trimester lasts from week 1 to week 12

The second trimester lasts from week 13 to week 26
The last trimester starts with week 27 and lasts until the end of the pregnancy, at week 40.

Numerous websites and books are available to the pregnant mother. With the help of these sources, she will be able to actively keep track of the developing baby, as well as the changes her body will most likely be going through. Each week has its own characteristics.

In the first two weeks, the body is preparing for fertilization or conception. It is not until the third week when the egg is actually fertilized and starts moving through the fallopian tube and into the uterus. The fourth week will bring with it the first pregnancy symptoms and most likely, a positive pregnancy test.

The pregnancy calendar of your choosing will have valuable information regarding any changes that you may experience after the fourth week. These changes are actually pregnancy symptoms. Some online calendars might also have detailed 3D imagery of your baby, tracing every step of its development.

The information provided by a calendar should keep you up to date with the general medical advice for pregnant women. These vary from certain exercises, pregnancy diets, partner implication in the process and even aspects that you might keep an eye out for (ectopic pregnancies or molar pregnancies).

If you are pregnant for the very first time, a calendar can really come in handy. Knowing what you should expect could spare your from worrying about certain aspects that are actually natural for the pregnancy stage you are in. Also, information provided for your partner could prove helpful for the support you will need all through the pregnancy.

There are fun facts in the calendars as well. For example, in the 27th week, the baby will be able to start recognizing your voice and in the 37th week it might follow a bright light with its eyes if you shine it on the abdomen. While these facts are not necessarily medically relevant, they provide insight for the parents and can get them more accustomed with the idea of having a baby.

A calendar is not a source of medical expertise. The information provided by such a calendar should only be used as an informative content and more in the purpose of entertainment. If any special or severe symptoms arise, the best thing would be to go visit your doctor in order to get a proper diagnosis. Also, your due date might not coincide with that presented in the calendar. Actually, most women will give birth between the 38th and 42nd week of pregnancy. Only 5% will deliver on their due date.

Chinese Pregnancy Calendars

The Chinese pregnancy calendar refers to an old calendar (dated somewhere between 1000 and 1300 AD) which was buried in a Royal Tomb near Beijing. It was supposedly created by Chinese doctors and astrologists to accurately determine the gender of unborn babies. Back then, there were no modern methods of determining the gender of babies and a lot of pressure was put on the matter. This was especially true for the royal family because only boys could become emperors and it was crucial that the ruler had an heir.

The Chinese calendar was supposedly drafted out according to lunar cycles which, the Chinese thought, could and will influence the gender of your baby. But is it really a viable method of determining the gender of your baby?

How does it work?

The Chinese calendar has a column which features the mother’s age from 18 through 45. Each column is divided into 12 rows, representing the months of the year from January to December.

For example, if you are a 27-year-old woman and you got pregnant in May then, according to the calendar, you will have a girl. If you would have conceived a month later in June, you would have gotten a boy.

If you get pregnant at 21, chances are you will have a baby boy except if conception takes place in January. At 18 years of age, if you conceive in January or March you will have a girl – any other month would result in a baby boy. Same goes for March and May if you are 30, the rest of the months will bring you a boy.

Modern day methods

There are numerous programs that allegedly provide you with the information needed to properly determine your future baby’s gender even before conception. This is the purpose of the Chinese pregnancy calendar as well. Natural supplements, intercourse positions and various lifestyle programs have gained a lot of popularity in the last few years due to the amount of information that we have uncovered about the conception process. But none of these are supported fully by science. It is agreed that, even if there are some things which could influence the gender of your baby (like pH levels in the vagina or cervix), it takes much more than a few factors to definitely determine such an elusive matter. The only way of determining a baby’s gender before birth is through ultrasound and even that method has its errors from time to time.

The game of chance

If you look at the whole story from a statistical point of view, things become rather clear. There is a fifty-fifty chance that a baby would turn out to be a boy. The same goes for a baby turning out to be a girl. Odds are that these methods have only gained popularity and credibility just by the mere game of chance that was played by all the parents involved. When the outcome is not what was expected, there are plenty of variables to blame. But if the baby turns out as the Chinese calendar had foretold, then it is a clear plus for it and a testimonial that it really does work.

In the end, there is certainly no scientific method yet developed to ensure that your baby would be a boy or a girl. While there may be methods that incline the odds in one way or the other, there is no such thing as 100% on this matter for now, not even with the Chinese pregnancy calendar.
