After feeling the early signs of pregnancy
, buy a pregnancy test
and took the pregnancy test, which was positive, the first thing I did (and I recommend you do), after celebrating with my partner, was to call my gynecologist to make an appointment.
One thing that caught my attention when I went for my first visit to the gynecologist, after I found out I was pregnant, was the cardboard calendar that was spinning while asking me what day my last period was. Soon after I found out what it was all about, it was a gestogram.
Today I am going to explain what it is, how to use it and I am going to show you everything you need to make your own gestogram
, gestational disc
or, also called sympathetically, pregnancy roulette
as it is reminiscent of a surprise roulette wheel.
What is a gestogram or gestational disc?
A gestogram is a graphical representation, usually circular in shape, that will help us to keep track of our pregnancy week by week
It also helps us to know the exact time of gestation, as a manual week calculator that tells us the week of pregnancy we are in and the approximate date when we will give birth (you can read more in this article "How many weeks pregnant am I?
How is the gestogram used?
Using a gestogram is very simple. As a rule, it consists of two concentric disks, disks that share the same axis. One of the disks is larger than the other and is placed under or behind the gestogram. The small disk is the one that we move in such a way that we make the mark or arrow drawn on it coincide with the date of the first day we had our last period, called LMP (Date of Last Menstruation).
With only this movement, we can obtain visually and very quickly the following data:
- Approximate delivery date
- Pregnancy week number
- Approximate Biparietal Diameter (BPD)
- Approximate femur length measurement (LF)
- Average weight
- Average size
What might you need your own gestogram for?
As we have already mentioned, with the gestogram you can quickly find out the approximate date you will give birth and the week of pregnancy you are in, but, as you may be thinking, you know these data by heart. The data that may interest you out of curiosity, and also for your own control of your baby's growth, are the data related to the fetus, such as the DBP, which is the distance between the two parietal bones of the head, the LF, its weight and its height. With these data, you will be able to validate the data provided by your gynecologist or sonographer, as they are directly related to your baby's development.
How do I make my own gestogram or pregnancy roulette?
The steps to make a gestogram are very simple. Below, I leave you a picture of the gestogram that we have made for you.
- Download the gestogram by clicking on the image below.
- Print and cut out the two discs of the gestogram separately. Try not to cut off the tip of the arrow, it will help you to point to the correct date. Print it on cardboard or heavy paper to make it more resistant, you can also glue the print on cardboard before cutting it out.
- Make a hole in the middle to ensure that the binder will be able to rotate properly. The bookbinder we will use will be a thumbtack type like the ones we used when we were kids for our craft portfolios.
- Join the two discs by passing the bookbinder through the holes in the following order: first pass the small disc and then pass the large disc.
Make sure it is tight so that it offers a little resistance and does not rotate without our help.
Once you have it ready, you just have to match the tip of the arrow with the day and month of your last period.
The weeks of pregnancy are marked on the outermost part of the small disk, the one that alternates bright pink and light pink in each number. If you look at the week marked 40, coinciding with it and on the large disk you will get the approximate date when your baby will be born.
Without turning the gestogram, we now look on the large disk for today's date, as we check the small disk at the same height and reading from the outside in, we will find the following values: the week of pregnancy in which you are currently, the distance between the parietals of the head of the future baby, the length of the femur, the approximate weight and, finally, the approximate size.
You already have your gestogram ready and you know everything you need to know to start using it. Carry it with you at all times and you can check at any time the week of pregnancy in which you are, the due date, ...
Note: The fetal biometric growth charts are elaborated on the basis of statistical data obtained by performing multiple measurements in a large number of patients, thus obtaining estimated mean values in a given population. You have to keep in mind that they are always indicative, never absolute values.
Do not forget that, if you have any doubts about your pregnancy, you should consult your gynecologist, he is the only one who will guide you properly during your pregnancy and will inform you correctly about the development of your baby.
The design of the gestogram is based on the http://www.facemama.com/ website.
