Even though I have no problem either
a lovely girl or a naughty boy, I choose the baby name since the first
week. Just in case we have twins. But if you would like to know the right sex of the baby, when will you know or will you have to wait for 3 months.
Although the baby's chromosomes
already determine whether your baby is a boy or a girl, with an ultrasound
or amniocentesis, you may be able to know a baby's sex before 3
months. In the genital period development, male and female genitals in the
fetus appear to be identical before about eighth week of pregnancy. At around
12 weeks, genitals have begun to differentiate, but these differences may not
be visible yet on an ultrasound.
