Not Ready to Be Pregnant

I really wanted to get pregnant a year ago. My boyfriend of 4 years and I tried for over a year and nothing happened so I finally decided it wasn't the right time.

But now I'm pregnant and worried that it's not the time. I mean I'm ready emotionally, but I'm still in college working toward my massage therapy license. I don't really have a job that's reliable when I need money. ... And my boyfriend has a heart condition and is out of work until he finds out about his insurance. To top it all off, I live in a house full of people who are very negative and unsupportive (other family issues)—and cats that are peeing in the house. I know that's not good for the baby. What should I do? I don't even know where to start.
