Is it possible to predict the gender of your baby using old wives tales about pregnancy? Some people certainly think so!

Old wives tales about pregnancy to predict the sex of your baby differ from the popular Nub Theory or the ancient art of baby gender prediction using a Chinese birth chart. This is because it’s less about definite dates or ultrasound scans and more about noticing changes, feelings and subtle signs throughout your pregnancy that might point to whether you are having a boy or a girl.



Some people swear by these old wives’ tales about pregnancy that have been passed down through generations. We’ve whittled down all the best ones below. From the classic ‘carrying the baby high or low’ and ramzi theory to particularly niche symptoms of pregnancy and bizarre pregnancy cravings that could all help you predict the gender of your baby before your 18 week scan.

So whether you’re eager to find out what the sex of your baby is before the scan or want a bit of direction to help you while thinking about baby names, have a browse through the most popular old wives tales about pregnancy below.


No theory this one! Now backed by many years of science. The nub theory is becoming the Internets number one go to for early gender predictions. This holds such a high accuracy, and is now known world wide. By far the best gender prediction to use from 12 weeks pregnant.


This theory is more for fun, yet its increasingly proving to show quite a high accuracy.

The ring gender test Tto predicit gender early is one of the many ways people have tried to predict the sex of their unborn baby. What makes this test somewhat unique is that one version also claims to be able to predict the number and sex of all your future children.

The ring gender test can be performed with using a simple threading of string through a ring.

Lie on your back and have your partner, family member, or friend hang the threaded ring above your belly.

Wait for it to move on its own. If it swings back and forth in a straight line  then this indicates a baby girl, if it goes around in a circle then it indicates a baby boy.


The baking soda gender test is an at-home method that involves combining a pregnant woman’s urine with baking soda to see if it fizzes. Whether or not the urine fizzes is supposed to determine whether the baby is BOY or GIRL.

The baking soda gender test actually looks to determine the baby’s sex, not its gender. The sex refers to their genetic and biological makeup, whereas gender refers to social and cultural differences that develop over time.

There is some science behind the test. Baking soda reacts with acids, causing some acids to fizz and bubble. The theory behind the test is that the acidity, or pH, of a pregnant woman’s urine, will change based on the sex of her unborn baby.

However, there is no proof that the sex of an unborn baby has any effect on the pH of a woman’s urine. Also, many other known factors can make a woman’s urine more or less acidic.

A woman who wants to try this test must collect her urine in a clean container the first time she uses the bathroom in the morning.

This first-morning urine must be used for the test because the woman’s urine may become diluted as she drinks fluids throughout the day.

It is important to wash the hands thoroughly before collecting urine. To collect the urine, a woman can squat over the toilet and hold the container under her while releasing a small amount of urine.

The next step is to add an equal amount of baking soda to the urine and look for whether the urine fizzes or remains the same.


The Mayans determined the sex of the baby by taking the mother?s age at conception, and the year of conception. If both are even or both are a girl. If one is even and one is odd?it?s a boy.
