Has anyone ever used that lunar calendar to predict the sex of your baby?

Nah coz i wouldn't trust it anyways.

u can try and do stuff like that...but it's just like flipping a coin 50/50....it's all fun but don't get ur hopes up...although i did that needle over ur wrist one and it said my first would be a boy...and i'm 31wks with a little boy....lol....

Well I looked at one of the lunar calendar's for fun, it said I would have a girl but I am actually having a boy. The best way is to let the doctor tell you what you are having.
