Pregnancy Cravings?

So I am just about 23 weeks pregnant, and so far I haven’t had any cravings. In the first trimester, I mostly only wanted carbs because they were the only thing that didn’t make me nauseous, but since morning sickness has passed, I haven’t craved anything unusual! I mean, I want Chinese food from time to time as much as the next girl, but I did before pregnancy, too! Anyone else not really have cravings? Are they really a thing? I feel like if you were low on a certain vitamin or nutrient you might crave those foods, but do others really crave ice cream or popcorn or do they just want it? I mean, I want bad foods sometimes too, but I did even when I wasn’t preggo. Thoughts?
