Am I out of line or overreacting? Am I crazy?

My husband and I have been trying to conceive for about a year. Within this time, 4 of my closest friends have become pregnant. In the past week, I found out two out of 4 of them were pregnant. It hit me harder than I'd expect tonight. I cried, and cried. And then I tried to pull it together. My husband comes home, asks me what's wrong, and when I tell him..he tells me I need to stop worrying so much about what my friends have and that I only want a baby so badly because they do. Which is NOT true. Now I'm questioning whether or not we should even be trying to create a life. I'm so upset and angry.
