God's plan or timing?

Rachael
I would like some input from other ladies who are dealing with or have dealt with infertility and who had to hear the "it's God's plan or timing" speech. As a Christian I don't know how to accept this. How is it God's will to bless a women with a child who abuses and kills it and not a women with a loving home and family? Advice in dealing with this frustration would be appreciated.
