I have no scientific proof to back this up, but I really think that elevated stress levels are really not helpful to conception. My theory is that if your body senses that you are anxious, you must have a reason to be frightened and that carrying a baby in a fight or flight situation is not good. So you don't fall pregnant.
My wife used to have a stressful job. We wanted children. It wasn't happening. She gave up work and pregnancy happened. It was financially very difficult at the time (despite the fact she'd paid into the system for 14 years and never had a day off sick, we got no maternity benefit because she left work prior to being pregnant), but we wanted children and made a life choice. Fortunately it paid off. Our eldest daughter was 6 today
Hardly scientific advice I know, but believing there are problems after a month is not going to help you IMO. You are both very young so no need to panic if a few months go by... Enjoy yourselves, relax and nature may well give you what you want.
Good luck
