"I need to know it will be okay"

Yesterday on my way to work, I was breaking down, falling apart. Work has been so stressful and both DH and I agree the stress is a big part of why I haven't gotten pregnant. (when you're so exhausted and busy you don't have sex, that will do it... When I do have sex it's forced and because I think we should) I've been really upset with all this recently because it's always been my dream to be a sahm, so I feel like I'm selling my life's dream for this job I don't want. But, with DH still in college, what choice do I have?
December is just around the corner. 7 weeks until he graduates to be exact. He's applying for jobs already even. The thing is that as close as we are, it feels so very far away. We figured out how much money he needs to bring in for me to be able to not work, and judging by the average salary for his field starting out, we'll be close... If he gets a good job, it's very do able. If not, who knows how long I'll be stuck working to make ends meet. The knowledge that this might not be over soon overwhelms me to the point of tears. This needs to be over soon, it needs to be.
That brings us to yesterday: me, crying in my car, begging God for it to be okay. For DH to find a good job, for me to get pregnant, and for it to all just be okay. Today, my neighbor calls. She doesn't know we're trying to get pregnant or that we're looking to buy a house at some point soon. (we currently live in a one bedroom apartment, if we're going to start a family we either need a bigger apartment or a house. We figure with the housing market the way that it is, we should at least look at houses.) My neighbor called to tell me that she dreamed about me last night. She dreamed that I lost a lot of weight (I'm already down by 15 pounds!) and I got pregnant, and DH got a job, and we bought a house. She started crying at this point because the house was farther away than she wanted it to be. She doesn't know this, but we're not looking in this area. Basically, she dreamed exactly what I'm hoping for.
I don't know that I believe in "signs". When someone dies and I see a butterfly, I think it's a pretty butterfly, not that the dead person wanted me to know that they're okay or something like that. Her dream, though, is just so perfect... Maybe I do believe in signs? And maybe I just want it to be a sign because I want those things to happen.
