Scared of the facts

2 years of trying and no baby.  My family doctor thinks I have PCOS.  I need to make an appt with my gyno, but I'm just scared.  I'm about to turn 30. What if I get the news that it's not going to happen?  It's such a lonely pain, grieving for the child that doesn't exist.  I have my husband but he just doesn't understand fully.
