Scrutenizing Friends/Family

I'm 22, married. My husband and I both have good jobs at a hospital, and are financially stable. Yet, friends are telling me I should reconsider TTC. It's so frustrating! Why? I'm ready for this step in life. It's not like I'm in highschool, or single, or unemployed. I'm trying hard not to be offended, because I know they tell me because they care, but I wish I had their support in this life decision. Did friends/family do this to you when TTC?
