How to Tell Your Best Friend You Got Your Period

# How to Tell Your Best Friend You Got Your Period

Getting your period for the first time is a big deal — and for a lot of tweens, the very first person they want to tell isn't a parent, it's their best friend. If you're trying to figure out how to tell your best friend you got your period, you're not alone, and there's no wrong way to do it. Whether you want to whisper it at a sleepover, pass a note in class, or just blurt it out on the walk home, this guide gives you real scripts and the confidence to use them.

I'm Nurse Al, a registered nurse and period educator at The Period Academy. I've talked to hundreds of tweens about this exact moment, and I can tell you: the friends worth telling are the ones who will make it a non-event — or even a celebration.

Why Telling a Friend Feels So Different From Telling a Parent

Telling a parent can feel logistical — you need pads, you need someone to explain what's happening. Telling a friend is different. It's social. You might worry about being teased, being seen as "grown up" before your friends, or accidentally making it weird. Some tweens worry their friend hasn't started yet and might feel awkward or jealous. Others worry the opposite — that their friend already started and will make them feel behind.

Here's the truth: almost every girl gets her period between ages 9 and 15, and most tweens are quietly wondering the same things you are. Telling a good friend usually brings you closer, not further apart.

How to Know If It's the Right Friend to Tell

Not every friend needs to know right away, and that's okay — this is your information to share on your own timeline. A friend is probably a safe person to tell if:

If you're not sure, you can always test the waters first by asking, "Have you started your period yet?" Their answer — and how they react to the question — will tell you a lot.

Scripts for Telling Your Best Friend

You don't need a perfect speech. Here are a few ways real tweens have done it:

The direct approach: "Hey, can I tell you something? I got my period today." Simple, calm, and to the point. Most friends will respond with genuine interest, not shock.

The text message: If saying it out loud feels like too much, texting first can take the pressure off. Something like: "Ok this is kind of a big deal but I started my period today lol" gives your friend a heads up and a chance to respond in a low-pressure way.

The "does this ever happen to you" approach: If you're nervous, you can ease in with, "Random question — do you ever get stomach cramps? I think I might be getting my period." This opens the door without a big reveal moment.

The note or message in class: For tweens who feel shy saying it out loud, a quick written note ("I need to tell you something at lunch, it's not bad, I promise") can buy you time to say it privately later.

What to Do If Your Friend Reacts Awkwardly

Sometimes a friend doesn't know what to say, and their first reaction might feel underwhelming or even slightly weird — not because they don't care, but because they're figuring out how to respond too. If that happens:

A slightly awkward reaction from a good friend almost never means they don't care — it usually just means this is new territory for both of you.

What If You Need Help From Your Friend at School?

Sometimes telling a friend isn't just social — it's practical. If your period starts at school, a friend can be genuinely useful: walking with you to the nurse's office, lending you a sweatshirt to tie around your waist, or grabbing a pad from your locker. It's completely normal — and smart — to have one friend who knows where your emergency period kit is kept.

When Your Friend Started Before You (or After You)

Periods don't follow a schedule, and there's no "right" order for friends to start in. If your friend already got hers, she can be an amazing resource — she's recently been through exactly what you're going through. If you're the first in your friend group, you're not "weird" or "early" — you're simply first, and your friend will likely come to you with questions when it's her turn.

Talking to a Friend Who Hasn't Started Yet

If you're telling a friend who hasn't gotten her period, be mindful that she might feel a mix of curiosity and nerves. Keep the conversation light and reassuring rather than dramatic. If she wants to know what it actually feels like, our guide on what period cramps actually feel like is a good, honest resource to point her toward — written specifically for tweens who haven't started yet.

The Bottom Line

There's no single "correct" way to tell your best friend you got your period — only the way that feels right for you and her. Most tweens find that once they say it out loud, the moment passes quickly, and what's left is just two friends who know each other a little better. If your friend is someone who's kept your secrets and shown up for you before, she'll almost certainly show up for this too.
