How early can pregnancy cravings start?

Livy

If I’m pregnant, which I have my suspicions 🤰, then I’m only about 4 weeks along. For the last two weeks or so, I have been absolutely craving buffalo wings and I didn’t even like buffalo wings before. But I seriously can’t stop eating them and they’re the only spicy food I’ve literally ever liked 😂 could this be a pregnancy craving? I haven’t had any aversions really so I’m just wondering
