Eating well balanced meals?

Hello all! Took out my implanon on 12/9 we are ttc for baby #2. Our first child is 5. I've had the implanon for 5 years, so I'm worried if it will take longer to conceive. Anyways got AF on 12/11-12/15. My doctor told me to eat healthy well balanced meals to cut out caffeine as well. Any recommendations on healthy well balanced meals? Also she prescribed prenatal vitamins which I'm not fond of :\
