Am I wrong?

My fiance wants to continue trying to conceive. Originally, I was on board with it but I just had a D&C almost 4 weeks ago now my whole perspective on it has changed. We have a trailer we rent and we are both working full time plus I am in school part time. I now want to hold off until I finish my degree which would be another 2 years. I want us to have a home that we own, I want the baby to have a nursery and a pool etc. I want to spoil our child when I do have one and I can only provide that when I finish schooling. I told my fiance I was going to get on BC and he now has an attitude because I keep going back and forth with the whole baby thing. I feel so conflicted, I want to make him happy but I also want to be happy as well. He already has a daughter that is little so I'm not sure what the issue is.
