Girl's name...?

Misty
We named our son with the same initials as my husband CTG. So now that we are pregnant (14 yrs later) we are still wanting to keep that tradition or either use my initials MSG. 
We find out in two weeks if we are having a boy or a girl.... so we are trying to narrow down names. We are 99% set on a girls name and still working on a boys name. 
But I have gotten some kick back from family for our choice of girls name.

Many say it is a boys name, she would be picked on her whole life, no one would never know if she was a boy or girl when registering for school or events, how will it look on her resume? 
We still love it!! But do you feel she would encounter these issues, and struggle in life?
