Not married Yet but we are ttc.

So we are both 23 and have a very big history together. We were suppose to be married before at 19 while my father was still around (he had pancreatic cancer) but he got cold feet and left a month before the wedding. We dated 3 years before that. We both had tried to move on, but neither of the relationships we were in worked out (He was in the marines and quickly married a girl who just wanted the benefits so theyre finishing finalizing the divorce). He came back and things are great. Been together almost 11 months now and live with eachother and we are both in agreement for ttc now, but I graduate this Dec. with a bachelors degree. I have no problem with finishing my degree while pregnant but my family on the other hand Im not sure they would be as excited for me. We do plan to get married but is bad to want a baby before hand? I just feel very conflicted and want to enjoy it.
