I second this. You can focus on eating healthy later in pregnancy. My first trimester and half of my second trimester I also lived off lemonade (on the sour side), crackers, and occasionally a peanut butter sandwich (most times, I'd wake up at 4am starving and I've had that then). It didn't matter WHAT I tried to eat, it never looked, smelled, or sat right with me. I had trouble walking through my work kitchen at noon because everyone was microwaving their dinners and I felt like vomiting just smelling it all. During my first tri, prenatal and folic acid also made me sick - and I mean, I'd take a capsule and puke it later.

Also be prepared to not like the same stuff you used to once the nausea subsides. I used to be big on salads, poultry and fish. Now, not so much. I eat broccoli with my meals, or I'll have spinach and mushrooms in my omelettes but that's it. Haven't touched poultry not fish since getting pregnant, but love a good steak.

Never used to eat fruit, now eat 6-7 portions a day. Everyone told me I'd get GD if I wasn't careful, but it's a myth, you only get it if your body can't metabolize sugar. Someone who eats 12 donnuts a day could still not get it. My mother who despised sweets when pregnant and only had salty foods had GD.

And when you say all you eat is crappy foods - try to be careful. I mean, there's a difference between saying all you can eat is bread vs. all you're eating is pizza and chips. Try to stay on the healthy side of "crap" food if you can.

My SIL gained 100lbs overall during her pregnancy because she would seriously only eat crappy food. And tons of it. So you still need to be careful. But you're on the right track - asking about getting your veggies in and all! :)
