20-something, stressed, and TTC

Hey y'all. Let me tell you a little about me. I'm 25, though I'll be 26 in a few months. I'm a first-year-teacher so my stress level is through the roof, and my fiance and I have just started TTC. I just feel as if this is the perfect time to start a family, and give the love of my life his first child. This would be my first pregnancy, so I am nervous, scared, and I am worried I am not going to be good at carrying our child. I like junk food, and I worry that the stress of my career will harm my conception attempts, and possibly my baby if I do manage to conceive. Don't get me wrong, I don't constantly live in fear or anything. I have bad, and good days. I guess I'm just looking to hear from some experienced moms, or those who feel the same for some advice, or encouragement. What do you all do? What is it like to carry your first child? Can you be a teacher, and have children without going bananas, lol?
