Oh Jen, I'm so sorry!
I wish your brother would have been more sensitive to you and your feelings. Don't feel silly about wanting to have the first grandchild. It is understandable. Even being preganant now I sometimes feel like I am "behind" in a strange sense when I talk to other preg. women due before me. I have to tell myself that I can't change it so relax. I'm glad you talked to your mother and you sound very positive for this IVF cycle. You know that all of us here on CT are praying for you!! Super BIG (((HUGS)))!!! Focus on taking care of yourself!! This will work!
