Consider the ultrasound technician's evaluation to be accurate; most won't make a prediction unless they get a clear view of
the baby's genitals.
Trust the results of your amniocentesis, if you have one.
Thread a needle or use a necklace with a charm and have someone else suspend it above your belly. If the needle (charm) swings
back and forth, a boy is in your future; if it moves in a circle, count
on a girl.
You've got a boy if your belly bulge is high up on your abdomen; carry low, and you're having a girl.
Breaking out often? Feeling extra-bloated? Many people would say that you're having a girl and that she is already stealing your beauty.
Looking back to the moment of truth - if the act that led to your conception was performed standing up, you'll have a boy; if the woman was on top you'll have a girl.
