(FYI) Stuff to know about your menstrual flow

Periods are totally normal & 100% natural

Nearly half the world has a period — it’s very normal and so not gross! And while your period may feel like an inconvenience at times, it’s also a sign that your body is strong 💪, healthy 🌳, and doing what it’s meant to do. 🔴

Every period is different

Not only are periods different from person to person 👯, but you’ll have all kinds of flows in your lifetime (some will be light, others will be heavy). Don’t believe us? Just ask your bff/mom/cool aunt/fave teacher what theirs is like — you may learn a thing or two about your own. ✅

It won't look or feel like a total mess

The average period is 10 - 35 mL of fluid over several days — measure that out to understand *exactly* how little it really is! Thinx (BTWN) is made with super-absorbent, quick-drying fabric that holds moisture in, so it won’t spill out when it’s time to change pairs. And it won't feel wet! ✌️

Feel better, naturally

Whether physical or emotional, a lot of people don’t feel like themselves during that time of the month. Try natural remedies to ease your symptoms: a hot water bottle 💦for cramps, a more supportive bra 🌀for achy boobs, and healthy snacks 🥑to balance your mood.

You can do anything on your period!

It’s true: you can bend upside down, go swimming, wear white, or hang on the couch all day long (along with a zillion other activities). Periods are just another part of life, and your flow shouldn’t stop you from doing *anything* you want to do. ⚽🌈🔬🎧🚲


Every person and every period is unique. Over time you’ll get to know yourself and your flow better—and we’ll have your back while you figure it out.

Period FAQs

( Q )
How long does a period last in one month?

The amount of time you’ll bleed every month can vary from 3 to 7 days, but it’s normal for your period to vary a little from cycle to cycle. If you notice blood for longer than 7 days, it’s a good idea to check with your gynecologist to make sure everything is okay.
( Q )
Can I swim and play sports on my period?
( A )
Absolutely! You can do *anything* on your period—swim, dance, wear white pants, go camping, whatever—you may just want to use different period products depending on the activity.
