should i tell my BFF that i got my period?

You totally can tell your BFF you got your period! It's like, a big deal, and if they're your best friend, they probably want to know what's up with you.

Okay so, telling your friends can be really helpful. They might already have their period too, and then you have someone to talk to about it. Or maybe they don't, and you can be the cool one who explains everything. My friends and I literally tell each other everything, and talking about period stuff just makes it feel more normal and way less dramatic.

But also, there's no rule that says you HAVE to tell anyone if you don't want to. It's totally your choice and when you feel ready. If you decide to tell her, you could just be like "hey, I got my period today!" or you could wait for a moment when you guys are just hanging out and talking. No pressure, just do what feels right for you and your friendship.
