The "right" time to try again

I had missed miscarriage in September, I was 11 weeks baby stopped growing between 8-9. I got pregnant right after but that but it ended in miscarriage as well at 6 weeks, my doctor said after my period this month I can go ahead and try again. BUT I turned in my nursing school application this month for the fall program. There's a 50/50 chance I'll get in. I want a baby so bad that it hurts, I don't want to put having a baby on hold, but I don't want to put school on hold either....I'm only 25 so yes I know I have plenty of time but my husband will be 33 and when I mentioned waiting he seemed really sad. I think about this alllllll the time
