Calculator boy or girl

If you are pregnant and you want to know the sex of your baby, with our boy or girl calculator you will be able to find out. To find out if your baby will be a boy or a girl, our tool is based on the Chinese pregnancy chart through which, the ancestors claimed to be able to predict the sex of the baby taking into account the age of the mother and the month in which the baby is born.

Are the results of the boy or girl calculator reliable?

As we have already said, the results offered by the tool to calculate the sex of the baby are based on the Chinese pregnancy calendar and although it is a very old belief, scientifically there is no reason to have a relationship between the results of the calendar and the gender of the baby. Because of this, the only reliable 100% result that will answer your doubts will be see your doctor so that, after an ultrasound, it will reveal whether you will give birth to a beautiful baby boy or girl.

Below is an example of the chinese pregnancy chart boy or girl or so you can take a look at how the data is organized depending on the age of the parent and the month in which the baby will be born.

Chinese pregnancy chart to find out if it is a boy or a girl

Boy or girl according to the Mayan calendar

The Mayas also had their own method for predict the sex of the baby based on the age you were when you became pregnant and the month in which conception occurred.

For the result to be as reliable as possible, you must add 14 days to the last day of your menstrual period, so you will know the month in which you became pregnant.

For example, imagine you want to to know if you will have a boy or a girl according to the Mayan calendar below. If you are 28 years old and got pregnant in July, the sex of the baby will be male.

Mayan calendar to know if it's a boy or a girl

As with the Chinese pregnancy chart, the Mayan calendar is not a reliable 100% source either, although it certainly allows you to place bets on whether you will have a pregnancy. a boy or a girl and then see if the Mayan predictions have come true.

Other home methods to know if it is a boy or a girl

In addition to using our pregnancy calculator boy or girl based on the Chinese table or the Mayan calendar to predict the sex of the baby, there are other homemade (and unreliable) methods that will allow us to know if we will have a boy or a girl. Here are some of them:

The heartbeat

If the first ultrasound does not reveal the sex of your baby but you have the heart rate of your heartYou can use this data to calculate its gender. If it has more than 140 beats per minute it will be a girl and if it has less, it will be a boy.

Red cabbage and urine test

There is a myth that allows to know if we will have a boy or a girl from the cooking water of a red cabbage. You mix a few drops of your urine in it and if it turns purple, it will be a boy. If the color of the water turns pink, it will be a girl.

The experiment is curious to say the least.

Ring and rope

I think this is one of the most widespread home methods to try to find out whether or not a boy or a girl will be born. Just find a ring that you really like and tie a string around it.

Now ask someone to hold it by the string and place it on your belly. If the ring swings like a pendulum (describes a straight line) then you will have a boy. If the ring moves in a circular motion, a girl will be born.

How to confirm whether it will be a boy or a girl?

Boy or girl?

The ultrasound is the medical test that will confirm whether you are having a boy or a girl. Some doctors may be able to sense something with the first ultrasound but usually, the baby's sex is confirmed on the second ultrasound scan that takes place in the 20th week of pregnancy or in some cases, two or three weeks before.

Thanks to the ultrasound scan, in addition to confirming whether or not it will be a boy or a girlYou will also be able to enjoy the baby's heartbeat, confirm that the baby's development is proceeding normally and other medical factors that serve to verify that everything is normal.

There are other tests that help to know the sex of the baby, but the most common is to resort to the second ultrasound scan to determine the sex of the baby. clearly see the genitals of the fetus and thus to clarify any doubts.

You may read on some sites that amniocentesis is useful to know if it is a boy or a girl, but the truth is that this medical test is only performed if the doctor observes complications in the fetus. It is a rather intrusive test that extracts amniotic fluid through the use of a needle and in some cases, it can induce miscarriage. Therefore, a doctor will never try to check the baby's gender by amniocentesis.

    • Hi Silveria, if the date of your last period was December 13, the child will be born approximately on 09/18/2016. You can calculate it at

      Therefore, how old you are is irrelevant to whether it is a boy or a girl.

  2. Buenas tardes Analia, he cumplido 50 años y me pone que está para 16 diciembre. Quería saber si niño o niña.
    Con dicha edad no puedo saberlo, pone hasta 45.


    • Hola Elisa,

      Lo primero de todo, enhorabuena por tu futura maternidad. Lamentamos que la tabla china del embarazo no contemple edades más allá de los 45 años. En cualquier caso, pronto saldrás de dudas en tus ecografías. Esperamos que todo salga bien!
