I really don't want my little sister talking about when I get my first period, but I haven't gotten it yet. How do I handle this?

Okay, so it sounds like you're worried about your little sister spilling the beans about your first period when it happens, and you want to be ready. That's totally fair, you get to decide who knows about your body stuff.

First, you can have a chat with your sister, even before anything happens. You can tell her that when you get your period, it's something personal and you don't want everyone knowing about it. You could say something like, "Hey, when I get my period, it's kind of a private thing, and I'd really appreciate it if you didn't talk about it with other people." Most siblings get it if you explain it calmly.

If she's super young, she might not totally understand what "private" means yet, so you might need to remind her a few times. You can also talk to a grown-up you trust, like your mom or another family member, and let them know your concerns. They can help you talk to your sister or help make sure your privacy is respected when the time comes. This is your body and your news, and you get to control who knows. You're totally in charge of that.
