Another baby?

My baby is turning 3 months old in about 2.5 days. My husband already wants another baby and keeps begging me to try. 
I want another baby too, I just don't know if it's to soon to start trying already. Also, we live with his dad and I'm not sure how his dad would react if we already get pregnant again, or even before we move out on our own. 
How long did you, or do you plan, on waiting between your kids? I want my kids close together, not more than 2/3 years apart.
