Tired

Well I just found out my best friend is pregnant. All my friends are either pregnant, just had a baby, or about to pop. I'm at the point where I am tired of putting on a fake happy smile and saying congrats to everyone that I really don't mean. I tell everyone and I tell myself that I'll get pregnant when I get pregnant. It will happen when the time is right and when I'm meant to be pregnant. I just don't know how much more I can take. My husband and I have been trying for a little over a year. I know it will happen eventually as we have 2 wonderful crazy daughters, but man it gets frustrating
