any moms have two of one sex and then on their third pregnancy have the opposite

Basil27

I have two wonderful little boys and I am currently pregnant with our third baby. I am really hoping for a girl! However my husband comes from a large family 11 kids and only two girls and both the girls were the last two pregnancies. So I think I am kinda expecting another boy but really hoping for a girl. I was just wondering how common the three kids of one sex are oppossed to 2 of the same and then getting the opposite on the third? Thanks ladies! 

fyi.. I will be completely fine if the baby is a boy!:o) just hoping for a girl
