advice from moms please!

I decided before pregnancy that I was going to get my MSN degree which is 2 years full time. I also need to fulfill some prerequisites beforehand. with that, I have 4 prerequisit classes I need to take. the spring semester runs from January- May 5th. I am due May 1st. I can take 1-3 classes during the spring semester. so the big question, do I get a head start on these prerequisites & cross my fingers that I don't go into labor before finals, or just continue to work full-time and save all my money and take the classes later down the road when I'm more settled with the baby?
