Signs your first period is coming

Everyone's experience is different, but these are the most common things to watch for:

Light spotting — may be brown or pink at first before becoming bright red
Mild cramps — a dull ache in your lower belly or back
Extra tiredness — your body is working hard behind the scenes
Mood changes — hormones are real, and they can affect how you feel
White or clear discharge — can start 6–12 months before your first period
Breast development, body hair, and growth spurts — all signs puberty is progressing

Pro tip

If you're noticing any of these signs, now is a great time to put together a period kit — before you actually need it.

What to keep in your first period kit

Having supplies ready means you'll never be caught off guard — whether you're at home, school, or a friend's house.

The essentials

Period protection — period underwear, pads, or both. Period underwear is the easiest starting point.
Spare underwear — one clean pair in your bag or locker, just in case
A discreet carry pouch — keeps everything organised and easy to grab
Pain relief — ibuprofen or acetaminophen if your parent/guardian approves
Heat patches — stick-on heat patches are small, discreet, and great for cramps

Cheeki tip

Our Carry Pouch is designed exactly for this — waterproof, discreet, and fits in any bag.

Why period underwear is perfect for first periods

Pads can feel bulky. Tampons can be intimidating. Period underwear removes all of that stress.

How our 4-layer protection works

Moisture-wicking top layer — pulls wetness away from your skin immediately
Super-absorbent core — locks in your flow so you stay dry
Leak-proof barrier — stops anything escaping, even on heavier days
Breathable outer layer — soft and comfortable all day long

The result? Up to 12 hours of protection that feels like just wearing regular underwear.

Which absorbency do you need?

Medium flow

Holds ~30ml

Great for school days, lighter flow, and your first or last period days. Slim and barely noticeable.

Shop medium →

Heavy flow — most popular

Holds ~50ml

For heavier days, overnight, and sleepovers. Soft and reliable without any bulk.

Shop heavy →

Not sure?

Start with both. Most teens use medium for school days and heavy overnight. That's exactly what the Teen Starter Kit includes.

Managing your period at school

Keep supplies in your locker and backpack — 1–2 pairs of period underwear, spare underwear, and your carry pouch
Track your cycle — apps like Clue or Flo help you predict when your next period is coming
Wear dark bottoms on nervous days — black leggings or navy jeans give extra peace of mind
Tell a trusted adult — a nurse, teacher, or counselor can help if your period starts unexpectedly
If you leak — stay calm, tie a hoodie around your waist, head to the bathroom, and rinse with cold water (not hot)

Frequently asked questions

How long will my first period last?

Typically 3–7 days, though it could be shorter or longer. Everyone's different, and your first few periods may vary.

Will my periods come every month?

Eventually, yes — but your first few cycles are often irregular. It can take 1–2 years for your body to settle into a predictable pattern.

Can I swim or exercise on my period?

Absolutely. Period underwear is great for most activities, though you'll want a tampon or cup for swimming. Don't let your period stop you from living your life.

What if I get my first period at school?

Don't panic — go to the bathroom or school nurse. Most schools have supplies available. If you're already wearing period underwear or have a kit in your locker, you're already prepared.

Is it normal if my period is really light or really heavy?

Yes, both are normal for first periods. Talk to a doctor if you're soaking through protection every hour or feeling dizzy.

What if I'm the first or last of my friends to get it?

Completely normal either way. Every body develops on its own timeline. There's no right age.
