HeadsUpDaddyYour daughter got her first period. What does a dad need to know?
Mostly: have the supplies, say less than you think, and do not make her manage your discomfort on top of her own.
The first two years are irregular, and that is normal
Early cycles are frequently anovulatory, which is a technical way of saying the timing hasn't settled. Gaps of three weeks or three months are both common in the first couple of years, and irregularity on its own is not a sign that something is wrong.
This matters practically: any prediction made from the first few cycles will be poor, and treating it as reliable will make you look foolish and her feel monitored. The useful thing early on is a record, not a forecast.
What to have in the house before it is needed
Pads in more than one absorbency, in a place she can reach without asking. Ibuprofen, which is genuinely more effective for cramps than paracetamol for most people. A hot water bottle. Spare underwear she does not have to request.
Buy them before they are needed, and do not make an announcement of it. The single most useful thing here is that she never has to start a conversation in order to get a basic supply.
What to say
Less than you are planning to. "There's a stock of everything in the bathroom cupboard, take what you need, tell me when it's running low" covers most of it and costs her nothing to receive.
Do not make it a milestone moment unless she wants one. A lot of the discomfort teenagers report about this is not the biology — it is being watched having a feeling about it.
If she is in real pain, believe her the first time. Period pain is routinely under-treated, and pain severe enough to stop her going to school is worth a doctor rather than endurance.
If you are doing this alone
Single fathers get very little written for them here, and most of what exists assumes a mother is handling it. The practical answer is the same as above, minus the assumption that someone else has covered it.
Knowing roughly when to expect it is worth a lot: it is the difference between a stocked cupboard and a trip to a shop at an awkward moment. That is the only thing this app is trying to do for you.
IN THE APP
How a daughter profile is different
A daughter profile is locked to the plainest tier. The humour tiers are not merely switched off for her, they are unavailable, and the fertility features are structurally absent rather than hidden. She gets the same tracking and the same warning ladder, with none of the jokes and nothing about conception. The app also will not create the profile until you confirm she knows.

Her period · day 2 of 5
Usually the heaviest days. Keep the bathroom stocked without making it a conversation, and don’t schedule anything demanding.

Quick check
Does the house have pads or tampons and pain relief before her period starts?

In the first year or two, a lot of variation is expected. Cycles consistently shorter than 21 days or longer than 45, bleeding lasting more than seven days, or periods that stop for several months after having been regular are worth raising with a doctor.
Yes, always. The app will not create a profile until you confirm she knows. A teenager discovering she was logged without being told is a serious breach of trust, and the convenience is not worth it.
No. Daughter profiles are locked to the plainest tier. The humour tiers are not available for them at all, and the fertility features are structurally absent rather than turned off.
That is common and not a failure. Keep the supplies stocked, keep the offer open, and let her come to you. Being reliably useful is worth more than being talked to.
This is general information, not medical advice. HeadsUpDaddy is not a contraceptive and not a fertility treatment. If symptoms are severe, persistent, or affecting daily life, that is worth a doctor rather than endurance.
