Period 101

Start with what is actually happening.

No huge science lesson. Just the bit that makes the rest of your cycle make more sense.

Your period is not just the week you bleed

It's actually the final scene of something your body has been 'working' on all month.

Which explains quite a lot. Here you can explore what a period actually is, why your mood shifts, and what the hell is happening inside your body (it's a lot…).

What is happening?

Your body is resetting.

If pregnancy has not happened, the uterus sheds the lining it built during the cycle. Blood and tissue leave your body β€” that is your period.

How long?

Usually a few days.

In this guide, Period mode covers roughly days 1–5, while bleeding itself can commonly last around 3–7 days. Your exact pattern can be different.

Then what?

The next mode starts loading.

As bleeding eases, oestrogen begins to rise again and the follicular part of the cycle gets going.

Your period is one part of the story.
