How can I track my daughter’s period?
You can track your daughter’s period by noting the first day of each period, how long it lasts, and any symptoms she experiences, such as cramps or mood changes.
This can be done using a calendar, a notes app, or a teen-friendly period tracker like luna.
Tracking works best when your daughter is involved and feels comfortable logging it herself, with gentle support from you to help her build the habit.

Will tracking my daughter’s period make life easier?
If your daughter's just started her periods, you’ve probably noticed that everything feels a bit tricky.
She might forget when her last one was, feel embarrassed asking questions but quietly be panicking that something is wrong, or only realise her next one is due when it suddenly arrives at school.
We get it, because we've heard from thousands of teens asking us about this via the anonymous questions in our app, luna (more on this soon!)
You're therefore probably looking to help her track her cycle, so she can spot patterns over time, as she learns what a first period look like .
Tracking her cycle can definitely help her feel more prepared and less anxious, so it's the right idea!
It can also help you understand how to support her – especially if she gets cramps, headaches, or big mood dips, which many explore in our teen PMS guide.
But it’s also very normal for teens to be…well, inconsistent.
Periods feel new. Routines aren’t always their strong point yet. And they might resist anything that feels like “mum monitoring me.”
So we also understand why you might be looking to help her track her periods, and why you might be finding the right way difficult.
The sweet spot really is finding a way to:
- help her understand her body
- make her feel in control
- gently encourage the habit
- and still give her privacy
How can I track my daughter’s period easily?
You can track your daughter’s period by noting the first day of each period, its duration, and any symptoms, such as cramps, mood swings, or headaches.
This can be done using a calendar, a notes app, or a teen-friendly period-tracking app, and it works best when your daughter is involved and comfortable with the process.
A few approaches can work:
1. A simple calendar
Marking the first day of her period with a dot or colour can help her see patterns.
The downside is that it’s not always very private, can be quite manual, and isn't super smart in terms of seeing predictions.
2. A notes app
Just logging “Period started on {date}” can be enough in the early months.
It’s quick, but it also doesn’t help much with symptoms, moods or predicting what’s coming.
3. A period tracking app
This is where things become more reliable and genuinely helpful!
But here’s the problem (which you may well have come across in your research so far): most period apps were built for adults trying to conceive, track ovulation or log sexual activity.
Not super appropriate for a young teen.
Which is why so many parents now prefer starting their daughter off with luna.
How can luna's period tracker help my daughter?
luna helps teens understand their periods and wellbeing by providing age-appropriate tracking tools and clear, teen-friendly information.
It is designed specifically for 11-18-year-olds.
It avoids fertility predictions, adult themes, advertising, and peer-to-peer chat, and instead focuses on clear, teen-friendly tools that genuinely support understanding and self-awareness.
Here’s why parents love it:
luna lets your daughter learn about her body at her own pace
Most teens don’t want to ask their mum about every single symptom (even if you’re close).
For example, brown period blood can be perfectly normal, but for teens who are new to experiencing it, it can be the most embarrassing thing ever to ask about
luna is there to explain everything, from cramps and discharge to mood swings, hormones and cycle changes in a friendly, straightforward way – it's also all medically reviewed by NHS doctors!
luna's safe and private
luna has:
- no peer to peer messaging
- no data selling
- no ads
- answers and content reviewed by real medical professionals and safeguarding leads
So you can relax knowing she’s not being exposed to anything she’s not ready for.
luna helps her spot patterns and feel prepared
Your daughter can log:
- period dates
- flow heaviness
- symptoms
- emotions
- energy levels
- skin changes
- sleep
At the end of each month, she gets a personalised wrap-up video that shows her what’s been going on.
It makes learning about her body feel less overwhelming (and much more fun!)
Teens actually enjoy using luna
We built luna with teens, not just for them.
So it has:
- avatars
- rate your day sliders
- quizzes
- videos
- a really friendly, warm non-clinical design
When they enjoy using something, sticking with it doesn’t feel like a chore.
How can I set up the luna app as a parent?
There are a few ways you can get luna for your teen, so you can choose whichever is easiest!
👉 Download the luna app yourself (we are luna in app stores) sign up as a parent, and set them up with a membership from there by linking their account to yours
👉 You can purchase via our website – you'll receive a digital code via email which your teen then redeems in their app profile
👉 You can ask your teen to download luna, and they can simply use your card details to set up a premium account in their version of luna
We want to make this as easy as possible, so please do email us if you'd like any support setting up a membership! You can reply to this email or email hello@weareluna.app

Should I track my daughter’s period?
Some parents worry their daughter won’t remember to log anything, and that’s totally valid.
But teens do tend to build the habit once they see the benefit.
If you track it entirely for her, she may not learn to recognise her own patterns.
So finding a middle ground might be helpful: be involved enough to support, but not so involved that she feels watched.
Why is luna the best period tracking app for young people?
It’s the first major app that's been designed to include:
- puberty and early period education
- teen-friendly explanations
- safeguarding
- total privacy with no peer to peer interaction
Adult apps simply aren’t suitable for 11-year-olds.
How can I help my daughter feel confident with her period?
You don’t have to get everything perfect.
What your daughter will remember is how calm, kind and supportive you were at the end of the day – and the fact that you're here means you really care which is amazing!
Set her up on luna, and see just how empowered she can become by tracking her own periods!
luna gives her the tools, privacy and knowledge she needs, while giving you peace of mind that she’s learning safely.

FAQs
Should teenagers track their menstrual cycle?
Tracking can help many teens feel more prepared and less anxious about changes in their body. It can also make it easier to notice patterns in mood, pain, or energy.
Tracking works best when it feels supportive rather than controlling. Apps like luna are designed to help teens learn about their cycle rather than try to “fix” it.
What age should I start talking to my daughter about periods and tracking?
It helps to start conversations before the first period arrives, even if it feels early.
Many families begin talking about periods around ages 8-10, depending on development.
This makes tracking feel normal and practical rather than frightening when bleeding starts.
Is there a period tracker for younger teens?
Yes. Some period trackers are designed specifically for under-18s and focus on puberty, symptom tracking, and reassurance rather than fertility.
Teen-first apps like luna use simple language and age-appropriate content so younger teens can track safely and confidently.
What do teenage girls usually use to track their periods?
luna is an app that combines period dates with symptoms, moods, and body changes, which helps teens understand what is happening rather than just counting days.
Is it better for my daughter to track her period herself?
When your daughter logs her own periods and symptoms, she is more likely to notice patterns and understand her body and build up the habit over time.
Parents can still support by talking things through and helping build the habit, without needing to track everything for her.
Is there a hormone or wellbeing app for teenage girls?
Some teen period trackers also include wellbeing and hormone education alongside cycle tracking.
Apps like luna combine period tracking with information about mood, skin, energy, and emotional changes so teens can see how hormones affect everyday life.
