I went for three months and the doctor said it was a girl. Is it possible for me to worship Guanyin and change to a boy?

First of all: according to the law of returning to China, medical staff can't tell the sex of the fetus like patients. It remains to be seen whether the way you know the sex of the fetus is authoritative!

Secondly: once the sex of the fetus is determined, it is almost impossible to reverse it!

Repeatedly: Buddha and Bodhisattva also talk about the equality of all beings, that is, the equality of all beings is even more impossible for men and women to be unequal, so it is difficult for Buddha and Bodhisattva to agree to your request.

Everything is equal, and what goes around comes around. Don't insist, harm others and harm yourself! The health of both men and women is the most important thing for babies. Please ask the Bodhisattva to bless you to have a healthy baby!
