My Period Is No Where to be Found

Um, where is my period? It hasn't been here since the first of November. I haven't gotten it since then. The last time I had sex was October and I had my period right after that. But all of December...nothing? I'm so confused. I'm not complaining too much but I'm pretty sure it's supposed to be here by now. Has this happened to anyone before? 🤔
