Pregnancy Discussion

I have been wanting to have children for the past few years. I wanted to become settled by finishing me undergraduate degree, finding a good job, buying a house,  and finishing my Master's degree. I have accomplished all of those things. We bought our house a year a half ago. My husband has also had been at his job almost a year. Being that I am a teacher, I would like to time the pregnancy around my job - I would like to have the baby in the spring because I would like to have the most amount of time at home with the baby as possible. So, the window of opportunity would be between June - October, preferably between July and August. I know it's selfish of me to think that I can plan a baby, but it's just a hope because I would like to spend time bonding with my baby.
The closer the time got, it seems like my husband and I would argue trying. We haven't done anything to prevent pregnancy after I decided to stop taking birth control in February of this year. After discussing and even arguing over the timing of pregnancy, he decided that we can try. He is nervous for all the right reasons. He is worried about the financial responsibility, and providing for an expanding family. He also worries about things that I feel are totally uncontrollable. He worries about the baby being born disabled, sick, or even dying. He worries constantly. Yes, these are things to fear and be concerned about, but I feel that we shouldn't let fear and anxiety control our future.
We presently live a pretty boring life. We have both completed school. We work, come home, cook dinner, watch a little TV or read, and then it's time for bed.  We both realize we need something else in our life. Jonathan has really grown to love Kylie, his cousin who is 2 years old. He enjoys spending time with her. Little ones are just such a joy to have around. He realizes that having a child will be enjoyable (in addition to hard work). So hopefully, we get pregnant this month or in the next few months.
