Should I tell him I'm pregnant?

I just found out I'm pregnant – my boyfriend and I have been dating for seven months.  
Background: he is out of college and has a good job and I am still a junior in college. We spin a good portion a time together and we have a great relationship but not financially ready for a kid. He just bought a new house . We are still working on the marriage discussion. Having a kid might mess up a lot in our relationship and even ruin it, I am starting to believe. 
I am reaching out to the women asking about stories in advice from around/ about the situation. Love to hear you out about what you would do in my situation. I'm not implying any abortion either but on the hands of the matter.
