Am I being inconsiderate?

My bf isn't talking to me because I recently had a pregnancy scare & was freaking out. He's mad because I wasn't happy with the thought of being pregnant. I've talked to him over and over again about how I'm no where ready to have a child, especially without the commitment of marriage. He can't seem to get it through his head. 
He's two years older than me( 28 and I'm 26) and I can tell he's kind of having baby fever, especially because he has his life together (already done with his masters degree, has a good job), and I'm still in that process. I'm in college about to be done with my BA, and after I will (God willing) be going to graduate school. Am I being inconsiderate about the situation? How can I get it through to him that this is not the time to have a child? I want to have a good career, hopefully engaged or married and be financial set before I even think about bringing a child into this world?
