2. Rumors about signs of a baby boy
2.1. Morning sickness You may have heard that the severity of morning sickness is a clue about your sexuality. For girls, thinking is higher hormone levels. For that reason, you will experience more morning sickness.The truth is that morning sickness can vary with pregnancies.

A similar story revolves around hair growth. With a boy, your hair will be longer and shinier.
2.3. Cravings With boys, you crave salty and salty foods like pickles and chips. For girls, it's all about sweets and chocolates.
In fact, no conclusive studies have been done on appetite as an accurate predictor of gender. These cravings probably have more to do with your changing nutritional needs.
2.4. Heart Rate One of the most common gender myths revolves around a baby's heart rate. If the beats per minute are below 140, the baby is said to be a boy. Over 140, it's a girl.
Unfortunately, although this sounds more scientific, there is no hard truth behind it. A study published in Fetal Diagnosis and Treatment found that there was no meaningful difference between the heart rates of boys and girls during early pregnancy.
