Need opinions please

Do you think teen pregnancy is okay? I've been with a guy for 3 1/2 years and were engaged, I'm 19 and he's 20, were not gonna get married for a couple or few years from now. I'm just curious because my fiance loves kids and he always tells me he wants kids and he wants me to be pregnant, I love kids too, but I'm not sure if we should wait a few or couple more years or until we're married. Opinions?
