That just outright sucks, doesn't it? I'm sorry you have "friends" that are so inconsiderate. It's like the people who meant well when I miscarried and said, oh you're young enough, you can get pregnant again (yeah, 2 years and 3 more m/c's later)...
Hang in there sweetie. It may not happen according to "our plan" but you know it will according to "His plan." Have faith hon... I agree with the ladies, your turn will come!
