Tips on getting greens in and staying hydrated?

I’m 7 weeks today (this is my first pregnancy) and I have been really nauseous. Im finding it hard to drink water and eat healthy foods because they just make me feel sick. I usually eat pretty healthy and love all fruits and veg but lately the thought has been putting me off. Pretty much just been living off refined carbs. Crackers etc and adding cordial to my water or drinking fruit juice. I’m worried my little bub won’t get enough nutrients or that it could cause problems. Am I being too paranoid? Or does anyone have any tips to get more fruit and veg in and drink more water? Xxx
