how should I spell my babies name.

Br
I am always indecisive when it comes to things that are important to me.  I have decided to name my daughter due May 3rd Dyani ( pronounced De-Yani) but I'm not quite sure how to spell it.  As it is now most people assume it's pronounced Dii-ani or Dy-any.  Should I change the spelling to D'Yani or Deyani so that it's not so confusing.  Why
So you think?
