I think I'm becoming anemic but I ate a ton of dark chocolate...?

I'm really pale and I get dizzy when I stand up, and I think it's because I'm not getting enough iron, probably related to being a vegetarian, but today my mom bought a bag of dark chocolate squares (60% cacao) and I usually never eat chocolate, especially dark which is my favorite, so I had a bunch of those. I then looked at the nutritional information and each square had 5 percent your daily iron and I swear I had at LEAST 15 squares, probably 20 (they were small squares, 4 of them was approximately the size of an average Hershey's bar) so that's like 100% of my day's iron right there, plus all the other food I had like pistachios, a banana, blueberries, bean-and-lentil soup, and a piece of string cheese. Will that help? I don't want to be anemic. I mean I like being pale (I think it flatters my coloring) but I'd rather use sunscreen than risk my health. What else should I eat, like what can I do to help? For the past 3 days I've been on a field trip staying in a collage dorm, and I had a spinach salad with every meal and eggs every morning, will that help too? Idk. I don't want to ask my mom, she's already objective enough about my being a vegetarian.
