Can you tell the sex of a baby by the mother's heartbeat during pregnancy?

It is a common belief that the mother's heartbeat during pregnancy can determine the sex of the baby. However, there is no scientific evidence to support this claim. The mother's heartbeat is unrelated to the sex of the baby.

The sex of the baby is determined by the chromosomes of the sperm that fertilizes the egg. The mother's heartbeat, on the other hand, can be affected by a variety of factors such as physical activity, stress, anxiety, and even caffeine consumption.

While there are various methods that claim to predict the sex of the baby, such as ultrasound, amniocentesis, and genetic testing, none of these methods are 100% accurate. The only way to know the sex of the baby for certain is to wait until birth.
