Determining the gender of a baby during pregnancy is an exciting milestone for many expectant parents. While it may be tempting to find out as early as possible, accurate determination of the baby's sex typically occurs around the 18th to 20th week of pregnancy. This is when an ultrasound scan can reveal the genital development and provide reliable information about whether you are expecting a boy or girl. However, it's important to note that factors such as positioning, gestational age, and individual circumstances can affect the accuracy of these results. In some cases, healthcare providers may offer non-invasive prenatal testing (NIPT) or other genetic tests that can detect fetal sex earlier in pregnancy with high accuracy. It's always best to consult with your healthcare provider for personalized advice and guidance regarding determining your baby's gender during pregnancy.
