Baby Fever...

My husband and I have been married for a year and a half and I have pretty bad baby fever. The only issue is that I worry that having a baby would take the fun and spontaneity out of our great relationship. Let me be clear. I'm not worried at all that'd he'd lose interest and cheat on me and he'd be an amazing dad. My husband says he'd like to have like 2-3 years together before we try but Im not sure he's being honest to himself because we're not super careful even though we both carefully follow my cycle. (He follows my glow profile and has even done his own research) It feels like we have an unspoken rule of 'if it happens, it's means to happen.'
