The Baby question

We went to a going away party at a bowling alley last night. My cousin in-law is moving to Florida with her husband. Again we got the "when are you two going to have a baby?" We have definitely been getting that more and more lately. I am not sure how to answer that. When we start trying I really don't want to say, "We're trying" because for some reason I have a feeling that people are imagining us having sex and I don't want that. I just think it is so funny that people are all of a sudden asking us more and more.
