Is there any truth to when morning sickness starts if pregnant with a boy?

Studies have looked at the connection between morning sickness and the sex of the baby. Some researchers have found that pregnant women carrying girls might experience more severe nausea and vomiting, and some have wondered if this could mean that morning sickness starts earlier in those pregnancies.

However, the evidence does not show that morning sickness begins sooner when you are pregnant with a boy. Both boy and girl pregnancies generally show similar timing when it comes to the onset of morning sickness, which most often appears during the first trimester. Many factors, including hormonal changes and individual differences, can influence when and how you experience morning sickness.

If you have concerns about your symptoms or need more information on managing morning sickness, you can use a symptom checker to help understand what you're experiencing, though it's always important to discuss them with your healthcare provider. They can help you understand what is normal for your body during pregnancy and advise you if anything seems unusual.
