First Period Kit Checklist
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.
Runs entirely in your browser. No account, no email, and nothing you type is sent anywhere.
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.
Leave an item blank and it prints as an empty line with a tick box, ready to fill in by hand.
Your sheet
A4 · one page
To save a PDF instead of printing, choose Save as PDF as the destination in the print dialog, and set margins to None. The sheet is drawn in plain black on white, so it prints fine without background graphics.
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
- 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.
- 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.
- 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.
