Pros and cons of using a family member please

Hello!


I just found out a family member is willing to donate her eggs to me.


For those of you who have gone that route, please tell me the pros and cons.


I love her to pieces and she looks a lot like me and we have similar personalities, body frame and intelligence.


She is my favorite niece and we are super close. I actually didn't ask her, my sister did. I started crying when I found out so overwhelmed by the gesture.


If we do that then what do we tell everyone?
