Today you can find out with science (or with a game)

For a long time, the only way to find out the baby's sex was to wait. Today, however, information can come early, with accurate tests, clear images, or even fun games. The decision is no longer when you can find out, but how you prefer to do it.

The important thing is to understand what options exist, what level of certainty they offer, and how they fit with what you need.

Medical Methods: When and How They Work

There are two widely accepted clinical methods for determining the sex of a baby before birth:

• Fetal DNA analysis in maternal blood: Detects fragments of the baby's DNA from week 9. It is a non-invasive and highly accurate test.
• Morphological ultrasound: It is performed between weeks 18 and 22, when the genitals are already visible by ultrasound.

Both procedures are safe, painless, and do not harm the baby. The main difference lies in the timing and function of each procedure: while one analyzes chromosomes, the other displays real-time images.

Choose based on your emotional, financial, and health needs.

The most commonly used tests and their level of certainty

Fetal DNA test:
This test examines the mother's blood for traces of the Y chromosome. If it appears, it's a boy. If not, it's a girl. It also detects possible genetic disorders, such as Down syndrome.

• Precision: More than 99%
• When it is performed: From week 9
• Advantages: Early, non-invasive, dual medical function
• Disadvantages: It can be expensive and is not always covered by insurance.

Morphological ultrasound:
The classic baby image that thrills the whole family. It allows you to see the sex, but also to review the complete development of the fetus.

• Precision: Between 95% and 98%
• When it is performed: Week 18 to 22
• Advantages: Emotional, included in prenatal checkups
• Disadvantages: Sometimes the baby does not cooperate or the position makes it difficult to see.

Both methods are valid and complementary. Some parents choose both to confirm with images what they already know through analysis.

Apps, tables and curious predictions

In addition to clinical methods, there are a host of home and digital options that, while not scientific, remain popular. Some are purely for fun; others are family tradition.

• Chinese pregnancy chart: Crosses the mother's age with the month of conception.
• Sex prediction apps: They use basic data to generate automatic results.
• Pendulum methodA ring is suspended from the belly. If it moves in circles, it's a girl; if it goes in a straight line, it's a boy.
• Bicarbonate test: A mixture of urine and bicarbonate. If it foams, it's a boy; if not, it's a girl.

Do they work? No. But they generate laughter, stories, and heartfelt moments. Using them as part of the process can be a way to share excitement without taking it too seriously.

What you should consider before choosing a method

Every pregnancy is different, and so are the emotions that accompany it. Before deciding how to find out your baby's sex, it's a good idea to consider a few key aspects:

• Do you feel ready to find out now? Or do you prefer to wait and experience the surprise?
• Do you have medical reasons to get tested early?
• Do you have emotional support to manage anxiety or unmet expectations?
• What does knowing the sex mean to you?

There's no right answer. But the more conscious your decision, the more fulfilling the moment will be.

And remember: even the most reliable method can have a margin of error. Emotional flexibility is the best companion on this path.

It's not just about knowing... but how you live it

Finding out your baby's sex can be a beautiful experience if you approach it calmly, openly, and joyfully. Not all paths lead to the same excitement, but all can be memorable if you choose what resonates with you.
