Does College Stress Effect You a lot?

Hey Everybody, so my husband and I got pregnant last year in June 2016 (without trying) and we were really excited but unfortunately I miscarried 2.5 months later (mid-August)... ever since then we started desperately trying to conceive..... I know I have crazy hormonal imbalances and really irregular cycles that last from 35-45 days. But idk why it’s been so hard....

also I recently started nursing school, this semester and that’s definitely stressing me out so I know that doesn’t help. But either way, even before nursing school there was no luck for a year... any ideas or advice?
