How to calculate the birth of boys and girls?

According to the prediction table of boys and girls in Qing Dynasty, my mother is 25 years old. 65438+ 10 to 65438+2 months: female, male, male, female, male, male, male, male.

If you are pregnant in the first month, the solar calendar is February or March, and it should be a boy. I don't know if it's right. I read it in an old yearbook.
