Determining the gender of your baby based solely on the LMP (Last Menstrual Period) and delivery date is not possible. The gender of a baby is determined by the combination of chromosomes from both parents, specifically the presence or absence of a Y chromosome in the father's sperm. This cannot be predicted accurately based on dates alone. To determine the gender, you will need to undergo prenatal genetic testing such as amniocentesis or ultrasound examination during pregnancy. These tests can provide more accurate information about your baby's gender. It's important to consult with your healthcare provider for further guidance and information regarding prenatal testing options available to you.
