I just don't understand.

So. Hubby and I have been TTC for about a year and a half with no luck and no problems preventing conception other than it's just not happening. Well one of his friends and his wife just had their 9th child. They're in their mid 40s and have no trouble conceiving. They love and take care of their children very well but 9 is a lot.  It's beyond unfair that they have it so easy when we have so much trouble at only 25 years old....
