Baby Fever and ttc HELP

Jordan • Wife and mommy, at 24 my life couldn`t be better!
Okay so I just got married on the 10th of September. My now husband and I have been together for almost 2 years and we have always talked about having more children. He raises, love, and treats my 3 year old like his own and plays the main dad role in her life. We had a pregnancy scare about a week before the wedding and he was NOT happy. Then after the get married, like that night, he tells me, "if it happens it happens, I'm not gonna prevent it but I don't want you encouraging it" and he's all the time saying "oh this for the next baby.." etc. 
My question is, am I wrong for tracking my ovulation and wanting a baby now when he just wants it to happen whenever? 
I know it sound weird that we JUST got married and already want one but we both decided a long time ago that we didn't want huge age gaps with the children. And although there fact that he doesn't treat our little one any different, I want to give him a little part of him to have too. Someone who he's blood with in our family. 
Little tidbits- we are both 19, yes we are young but when you know you know. Not that I feel like I need to justify myself, but so no one says "you're too young, because 15 was young let me tell you. But we both have full time jobs, two brand new cars, a 4 bed 2 bad paid off house on 4 acres, and one happy little girl. We have our life together, and we wouldn't dare bring a baby into it if we didn't. We are young but we got this!
