Leg hair growth during pregnancy?

I know it's just an old wives tale but it had to of been true for someone if they made it up and passed it along. But I was wondering if anyone really found it to be true that their leg hair grew faster and thicker for boys (or just grew like normal) and then barely grew at all for girls. I have two boys and my leg hair grew like crazy, and this time around (even though I am only 6 weeks along), I only have to shave every few days, and its super thin. I know it all has to do with hormones but it is a little strange that my body is already reacting differently to this pregnancy. Has anyone found this old wives tale to be true?
