help!! please!!

*please no bashing!*

My husband and I have an 8mo son, whom we love dearly. My husband has also just recently sworn in to the Army and leaves for basic training at the end of the month. Until then he is essentially unemployed, he has picked up a few days at a restaurant we used to work at but other than that he has no job until he leaves. With so much going on, we also found out that we're expecting again. Absolutely not in the plan. Absolutely terrible timing. We do not want to get an abortion (mind you I am pro-choice I just never thought I myself would consider it), we both don't like the idea. However we cannot deny that right now that may be our best option. There's already a lot going on with him leaving for a few months and me taking care of our son and our dog on my own, but add in my pregnancy and it's insanely hectic, plus moving to wherever he gets stationed near the end of the year which would be around the due date of said pregnancy. Moving while that close... and financially we are in a horrible situation. As much as we dislike it, we need to keep our options open. 

What I want to know is, any mom's who have been in a similar situation, how did you handle it and did you regret it? Did you have a hard time getting pregnant afterwards because of it? We do want more children, but just my right now. Please help!!
