Graduate school & TTC

Long story short, my first pregnancy last month was ectopic. My husband and I weren't trying but it happened and it made us both realize we want a baby! I just found out yesterday I was accepted into a two year graduate program. While it is mostly online there are one day a week classes both years, and practicums the second year. My husband has been thinking of how I can do both, even saying he could stay home with the baby when I have school or practicum. He said it would be easier to be home with the baby my last year of school (since its 3/4 online) than dealing with maternity leave at a new job once I graduate. I'm worried about being pregnant in school, and having to miss a week or two for delivery. I want to try again so bad but do not want to mess this program up! What do ya'll suggest?
