As soon as you get pregnant there are number of people who tell you non-medical tricks for gender prediction.
Most of them have evolved out of old wives tales and are not accurate.
But they are all fun.
They range from the direction the wedding ring swings through the shape of a pregnant woman's belly to her craving for "manly" or "womanly" foods.
Many expectant mothers want to know their baby's gender so that they can plan a nursery for them, buy clothes, pick names for them and so on.
Trying different methods of gender prediction is fun because it is safe and harmless to the mother as well as the baby.
In ancient China, it was believed that having a baby boy or girl was in the mother's control.
They thought the women can change the sex of the baby during her pregnancy and she could do it until the third month of her pregnancy.
Other theories about determining a baby's gender were the moon and lunar calendars.
Some people think that the way a woman carries the baby is a good means for predicting whether the woman will have a baby boy or girl.
They say that boys sit higher while girls sit lower in the belly.
This is actually not true as there are many factors that influence the size as well as shape of the belly during pregnancy.
In today's modern time the easiest and affordable way to know the sex of your baby is the gender prediction test.
It is a simple in-house urine test that provides gender results within ten minutes.
It is mostly used as early as six weeks after the first missed period.
