Acidity has nothing to do with what kind of child you are likely to have, whether you have a boy or a girl is related to the chromosomes.
Whether a boy or a girl is born is determined by the male sperm. The chromosomes of the female egg are X and X, and the chromosomes of the male sperm are X and Y. If a male with a Y chromosome combines with the egg, a boy is born, and if a male with an X chromosome combines with the egg, a girl is born.
Therefore, the birth of a boy or a girl has nothing to do with the body type, and you can’t change the chromosomes by changing the body type. Don’t be superstitious about some unscientific methods to prevent harm to your body.
It is recommended to let nature take its course, do not have too much psychological burden, the baby’s health is the most important thing.
