Gender Bender

So, what'll it be? Boy or Girl? Girl or Boy?
Some parents wait until their due date to find out but I am that kind of really curious person who would peek at Christmas presents if I thought I wouldn't get caught!
Today is the day of our 20 week scan. Both my husband and I are hoping to find out the sex of our baby. Not that it matters mind you... I suppose we're hoping for a boy but only because of all the girls born in the family already (7 girls and no boys in the youngest generation so far).
There are a number of less scientific methods of predicting the sex of your baby. Are you hairy? It's a boy! Is the bump low? It's a boy! Is the bump high and visible from the back? It's a girl! Does your wedding ring swing like a pendulum over your stomach when suspended from a strand of your hair? It's a boy. Does your wedding ring move in a circle over your stomach when suspended from a strand of your hair? It's a girl. Is the fetal heart rate over 140? It's a girl. Do you crave cheese and meat? Boy. Do you crave sweets? Girl. Is your right breast bigger than your left? Boy! There are also various online quizzes which will tell you - mine have said boy. And last but not least if the year you conceived in and the age which you conceived at are both odd numbers then it's a girl.
It's all very confusing really so I'm really looking forward to something scientific today! Is it a boy? We'll see but we won't be disappointed either way.
