Why tracking your daughter’s period can 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.
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.
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 to track your daughter’s period (the simple options)
If your daughter is just starting out, you really don’t need anything complicated.
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.
Why luna works so well for teenagers
luna is the first period and wellbeing app designed specifically for 11–18-year-olds.
No fertility predictions, no adult themes, no dodgy ads, no chat features.
Just clear, teen-friendly information and tools that genuinely help.
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 do I keep track of my daughter’s period?
With luna, you don’t need to track it for her.
In fact, many teens feel more confident over time when they’re the ones doing it.
Your role can simply be:
- helping her set luna up by downloading the app and getting a parent account
- checking in occasionally to see how she's finding tracking
- gently reminding her if she's likely to forget
- supporting her when symptoms show up
- and helping her understand what’s normal
A simple: “Do you think your period might be due soon? Should we check the app together?” can feel supportive rather than intrusive.
How to 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 you track your 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.
luna is 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.
Helping your 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.
