What will my first period be like?

Whether you’ve been dreading it or totally desperate for it to arrive, your first period can feel like a leap into the great unknown. 

Will it arrive drip by drip, or all at once in a river? Will I look different? WILL EVERYONE KNOW?

Unfortunately there’s no period crystal ball to tell you exactly when it will happen, or where you’ll be when it does (please not assembly). And like your first day of school or your first ever burrito, everyone’s first period will be memorable in a different way. 

But here are some things you can expect.

Will I feel it?

Probably not. You might feel some wetness or stickiness in your pants, or maybe some slight cramps in your tummy – but there is no specific ‘bleeding feeling’ that announces your period is in town. Chances are you won’t notice at all until you next go to the loo.

What colour will it be? 

This will be different for everyone too – but we can promise you this much: it won’t be blue. 

Nobody really knows why olden days sanitary towel companies decided that bright blue liquid would be less scary than the real deal, but you can live safe in the knowledge that your monthly visitor won’t be a raspberry Slush Puppy. 

More surprisingly, period blood doesn’t often look like the bright red blood you see when you fall over and cut your knee either. For some that first appearance will be a pink-ish colour, while many people’s first period is often closer to brown than red – which can come as a bit of a surprise. Fact: you will not be the first person to wonder if they pooed themselves without noticing. 


Whatever the shade, don’t panic. Your reproductive system is just getting into the swing of things, and the colour will often become more red over time. But it will never, ever be blue. 

How much blood will there be? 

The amount will be different for everyone too. It could be a sticky discharge that only lasts a day or two, or ‘spotting’, which means bleeding lightly on and off for a few days. And some people’s first period might be quite heavy – but don’t panic, that doesn’t mean it will be heavy forever. 

Your first few periods might feel like a whole variety pack of changes, but things should settle down into a more predictable routine [link to how heavy should my period be?]. 

How long will it last? 

Your first period can last from anywhere between one and 10 days, and it’s also pretty common to have your first period and then not bleed again for a few months. Helpful, we know. 

For the first year or so your periods might be a bit all over the place while your body finds its natural rhythm, but things should settle down into a fairly predictable pattern [Link: How long should my period last?]. 




Honestly. You might feel like you’re walking around with a neon flashing ‘PERIOD! PERIOD!’ arrow above your head, but the truth is you look exactly the same as you did the day before. Nobody will know unless you choose to tell them. Or send out party invites.

But if you’re ready, it is a good idea to talk to an adult you trust. They can help you to get all the supplies you need – whether it’s pads, tampons, cuddles or a really big burrito. 

TLDR? Here’s the important stuff:

At least at the beginning, period blood will probably be more brown than red – but everyone is different. 

Some people will have a sticky discharge the first time, others will have light, on-off bleeding and some might bleed quite a lot. 

Your first period can last from anywhere between one and 10 days, and might not arrive again for a while. 

You can celebrate however you like (we recommend a dance party).
