How hard is it to be in college and be pregnant at the same time??? And when is the best time to be married?

So I have figured everything out... My bf is joining the Army this year, probably after this summer, he doesn't know exactly when, and I am devastated because we are already long distance and I thought we would finally be closing the gap soon but.. if he joins we won't be. Anyways I want to marry him but idk when the best time is, we talk about it a lot and he said after I graduate (2 years) but I want to get married like soon, I don't care about having a huge wedding, I would gladly go to the courthouse and do it because I just wanna be with him. So I want to maybe go see him in December and do it, but I know I can't rush him into it marrying me. But he wants to have a baby, and I was thinking about it and I don't wanna get pregnant this summer because i have an internship in the Fall and i want to be be able to have fun but if I get pregnant in December I could have my baby in September and I will be a senior, the only thing is I think it will be hard to raise it and care for if I am in school all day. But then again I have a daycare in my school so that makes it less difficult. I don't know I'm like stuck because I want to have a baby (and get married too) before he goes away but I have no idea how this whole Army thing works.
