I have a baby and want to get pregnant again!

I have a 6 month old baby, almost 7 months. And my husband and I really want another baby soon! I wanna get pregnant ASAP. But, I'm afraid of how I will manage time with both of my kids. Has any of you had babies so close to each other? If so, how did you manage to take care of both? Also, I am still in the University, will almost graduate in about 2 years. I know I should finish school first, but I really want my baby to have a brother/sister soon.
