So what should i put first? My career or family?

I am a 24yr old female. I have been married now for about three years, my husband and i decided we wanted a family, we have been working on having a baby now for about a month. Im not sure if im pregnant or not. But the problem is, sense we have been trying. I have gotten a few offers that I have been trying to get for years with this big modeling agency here in the ATL. I have been trying to get signed with this company for years. I am now scheduled for a big photo shoot on second of sept, the problem now is I think I maybe pregnant. I was wondering what others think about my situation, should I keep the baby or should I say focused on my career?
