Ever wondered what to expect on your first period? You’re not alone—so many girls (and moms!) have questions about the signs of puberty, what happens when your first period comes, and how to handle bleeding, cramps, and all the changes. Let’s keep it real, break down the facts, and talk about how Suyiyi bras and the right hygiene products can help you feel confident every step of the way.
What to Expect on Your First Period: The Real Signs
Your first period can start anywhere from 9 to 15 years old, but the average age in the US is now around 12—and it’s happening earlier for some girls. If you’re noticing signs of puberty like breast development, pubic hair, or vaginal discharge, your first period could be coming soon.
Table: Signs Your First Period Is Coming
| Sign | What It Means | When It Happens |
|---|---|---|
| Breast development | Breasts/buds start to grow | 1-2 years before period |
| Pubic hair | Hair grows in new places | Before or with period |
| Vaginal discharge | White/yellow stains in underwear | Months before period |
| Mood swings | More emotional, sometimes sad or irritable | Weeks before period |
| Pimples | Breakouts from hormone changes | Weeks before period |
| Cramps/abdomen pain | Achy lower belly or lower back | Days before period |
What Your First Period Is Actually Like
When your period for the first time starts, it might just be a spot of blood or a small stain in your underwear. The color of period blood can be light pink, bright red, or brown—all normal. Your first period might last just a day or a few days. Later, periods usually last anywhere from 2 to 7 days.
-
The amount of bleeding is usually less than you think—about 1–5 spoonfuls.
-
You probably won’t know exactly when your next period will come during the first few years, so keeping pads or clean underwear in your locker or bag is smart.
-
Track your period on a calendar or with an app to get a sense of your cycle and spot patterns.
How Your Body Might Feel
Common symptoms during your period include cramps in your abdomen or lower back, feeling bloated, mood swings, and sometimes headaches or loose poop. Some girls feel nothing at all, while others have heavier cramps or more intense symptoms, especially in the first few years after they start menstruating.
Tip:
A heating pad or hot water bottle works best for soothing cramps. If you don’t have one, a warm towel can help.
Hygiene Products: Pads, Tampons, and More
When your first period comes, you’ll need a hygiene product to catch the bleeding. Most girls start with pads because they’re easy to use—just peel, stick, and wrap the used one in toilet paper before tossing it. Some girls try tampons or menstrual cups after a while. If you use a tampon, make sure to change it every 4–8 hours to lower your risk of toxic shock syndrome. Always wash your hands before and after you insert or remove any product.

What To Do If Your Period Starts at School
If you get your period for the first time at school, don’t panic! Visit the school nurse or ask a trusted adult for a pad or tampon. If you get blood on your clothes, tie a sweater around your waist until you can change. Lots of girls keep a period kit in their locker or backpack just in case of an emergency.
After Your First Period: What’s Next?
Your periods might not be regular for the first two to three years. It’s totally normal if you skip a month or if your bleeding is heavier or lighter each time. Most girls’ cycles settle into a pattern after a while, but if you haven’t started by age 16 or if your periods are extremely heavy or painful, talk to a doctor or healthcare provider to rule out any underlying medical conditions.

Track of your periods with a calendar or app to notice patterns.

Stress, health changes, or developing bodies can all affect your cycle.
