Why isn't all this enough?

I feel so guilty right now. I have just about everything I ever wanted. I am happily married to the most wonderful man I have ever known! I am working full time, getting paid very well, in a job where I am using my degree! I am living in a beautiful townhouse! I have new friends out here in Ohio!

But...

Something is missing...

I want a child so much. I want to share my wonderful life. I want my husband and I to start a family, however, no matter what we do, I haven't gotten pregnant yet.

The hardest part is having all of my friends pregnant. Seriously I have at least 7 friends pregnant right now or just had their babies.

I know we have only been married for 6 months now and I know I am only 22. I also know that money is tight, but I have felt that there is something missing. I feel this is what we need to do. I pray every month that I am pregnant and the disappointment is so overwhelming. I need comfort, but I am not sure where to go for that.
