Doctor's answer:
During the third and fourth months of pregnancy, it is important to rest well, enhance nutrition, and avoid exposure to harmful substances. You need to go to the hospital for a check-up, where you can undergo a Down syndrome screening and a 3D/4D ultrasound examination to see if the fetus is normal. As for the gender, it can only be determined through a B examination.
