No, you cannot get pregnant while you are already pregnant.
Pregnancy occurs when a sperm fertilizes an egg, leading to the development of a fetus. Once a woman is pregnant, she already has a fertilized egg and a developing fetus in her womb.
The body undergoes significant hormonal changes during pregnancy, making it impossible for another egg to be released and fertilized. The cervix also closes off during pregnancy, preventing sperm from entering the uterus.
Therefore, getting pregnant while already pregnant is not possible.
