Micronutrients on veganism

Hello, i need help. I started eating vegan diet. Im scared of not getting enough micros. I supplement b12 but idk about others. Many people say Its hard to get zinc, iron, calcium, idoine etc. and it makes me nervous what else do i need to supplement. I eat oats+vegan protein+ nuts on breakfast, quinoa+tofu+olive oil+beans on lunch and lentils,seeds on dinner. Fruits And vegetables on every meal too. How can i Tell which micros am i missing ? Ty
