First Period Kit Checklist

A first kit is two short lists. For the school bag: two or three pads, a spare pair of pants, a small pouch to keep them in, a few wet wipes and a bag for wrapping. The rest stays at home. Periods usually start between the ages of 8 and 17, which is why the pouch is packed early.

A first period usually turns up without asking. A small bag packed in advance turns that from a crisis into an errand — so here is the list, in two parts, ready to tick and print.

Free, and no account.

Pack the kit

Two short lists. The first one lives in a school bag or a coat pocket; the second stays in a drawer at home. Change any of it — these are only the things most people end up wanting.

In the school bag
At home

Leave an item blank and it prints as an empty line with a tick box, ready to fill in by hand.

On the paper

It happens to most people in the building, and the staff deal with it constantly. A first period at school is an errand, not an emergency: ask a teacher, the school office or the nurse and they will have pads. There is nothing to explain and nothing to apologise for. The one item people say afterwards they wish they had packed is the spare pair of pants — everything else on the list can be borrowed.

Nobody can tell you the date, which is exactly why the bag is the useful part. The NHS says periods usually start between the ages of 8 and 17, or about two years after the first signs of puberty. That is as narrow as anyone honest will make it, and no page, quiz or app can shrink it to a week. Pack the pouch early and use it months later — that is the kit working, not the kit being unnecessary.

This is a packing list, not medical advice. Once periods have started they are often all over the place for a while; ACOG says it can take six years or more to settle into a regular pattern, and cycles of 21 to 45 days are normal at that age. Worth seeing a GP, per the NHS, if periods have not started by the age of 15, or if three are missed in a row once they have — and worth an appointment any time bleeding or pain is stopping normal life.

How this is worked out

  1. The list comes in two sections because a kit does: a small one that lives in a school bag or a coat pocket, and a fuller one that stays at home in a drawer. Everything on either list can be renamed, removed or added to.
  2. The sheet prints at true paper size, A4 or US Letter, with tick boxes big enough to use and a space at the bottom for the two or three phone numbers worth having written down.
  3. Nothing here is predicted or calculated. Periods usually start between the ages of 8 and 17, and no page, quiz or app can name the day — so the useful thing to have is a packed bag rather than a date.
Questions

The short answers

For the bag: two or three pads, a spare pair of pants, a small bag or pouch to keep it all in, a couple of wet wipes and a nappy sack or paper bag for wrapping. For home: a bigger pack of pads in a couple of sizes, night pads, painkillers if a parent is happy with that, a hot water bottle and something to make notes on. Six things in a pouch beats twenty things in a drawer nobody opens.
Before you think you need it. Periods usually start between the ages of 8 and 17, or about two years after the first signs of puberty, and there is no way to narrow that down to a week — which is exactly why a packed pouch is worth more than a prediction. Plenty of people pack one and use it months later. That is the kit working, not the kit being unnecessary.
It is a normal thing that happens to most people in the building, and school staff deal with it constantly. Ask a teacher, the school office or the nurse — they will have pads. If you are wearing something light and are worried, a jumper round the waist buys you the walk to the toilets. Keeping a spare pair of pants in the pouch is the single item people say afterwards they wish they had packed.
Pads first, almost always: nothing to insert, easy to check and easy to change in a school toilet. Period pants are excellent as a backup and need no bin. Tampons and cups are perfectly fine to use from the start if somebody wants to, but they are a lot to learn on day one, and there is no rush at all.
A period usually lasts between two and seven days. The next one may be a month away or it may be three, and for the first few years that is ordinary — ACOG says it can take six years or more after periods start for a cycle to settle into a regular pattern. Cycles of 21 to 45 days are all normal at that age. Writing the start date down each time is the one thing worth doing, because after a few months it stops being a mystery.
The NHS says to see a GP if periods have not started by the age of 15, or if you have missed three periods in a row once they have started. Also worth an appointment if bleeding is so heavy it soaks through a pad every hour or two, or if the pain stops you doing normal things — not because either is likely to be serious, but because there is usually something that helps, and nobody should be quietly putting up with it.
