Baby in college?

My boyfriend and I are both freshmen in college. Although it is far away, we are already talking about marriage and planning our wedding for May of 2013. Immediately following school he has to serve in the Air Force for 2 years and I will follow him. We have been talking for a while about wanting to have children early so that we could watch the many generations of children in our family grow up. We had a pregnancy “scare” (we thought I was but it turned out I wasn’t) last month and started getting excited and planning for our future and our baby’s future. Luckily, we knew it would be ok because A) he is very financially stable (making average (if not more) income for college graduate) B) we would have the support and love from our families and C) we were really happy and know we would be able to to do it together. After finding out I wasn’t pregnant, we were actually very disappointed. We are now debating trying for a baby. Any advice from someone who has been in a similar situation?
