How to Choose the Right Period Underwear for Your Flow

Choosing the right period underwear is not meant to be complicated. There’s already enough going on! Once you understand your menstrual flow and how you want to use them, choosing the right pair is actually pretty intuitive. Let's break it down.

First, get honest about your flow. You might breeze through your period with hardly a spot, or your bathroom could look like a 24-hour crime scene, or you might sit somewhere in the middle. All is normal. (Note: Unless it’s not - if you have any concerns about your cycle, please speak to your doctor!)

A simple way to think about it:

• Light flow: spotting, the tail end of your cycle, or days when you want a little backup. 

• Medium flow: your average period day; nothing dramatic, just steady and predictable.

• Heavy flow: the first day or two, overnight, or anytime you need maximum coverage and zero mental energy to spare. 

Your flow shifts across your menstrual cycle, which is exactly why most people end up with more than one pair type in rotation. That's not a complication, it’s preparation. 

Match the pair to the day (not the other way around)

This is where Undercovers period underwear genuinely earns its place in your life.

On lighter days, a light or medium flow style does the job without any bulk. Discreet, breathable, and barely-there, a light flow pair is also suitable for discharge during your cycle or if you’re a sweaty betty at the gym.

For your medium-flow days, our medium absorbency styles - such as our bikini or boyleg - are your workhorse. Enough coverage to get through a normal day without constant checking or changes. Reliable in the best, most boring way. These ones are also great for light bladder leakage.

When things ramp up, you want the Heavy or Super styles with the highest absorbency. Our absorbent layer runs the entire length of the underwear, not just the gusset so you can put these one, forget about them, and actually sleep through the night. Worth every cent.

The goal isn't finding one magical pair that does everything. It's having the right options for the different versions of your cycle.

Think about how you actually want to use your period underwear 

There's no single right way to do this. Some people go all-in and ditch pads and tampons entirely. Others use period underwear on light days only, or as a backup when you need an extra layer of confidence. Some people only use them overnight. You do you, babe!

If you're new to period underwear, start low-stakes - try them at home on a lighter day, or as backup while you sleep. Get a feel for how they work for your body before wearing them to a big meeting or a long day out. Confidence builds quickly once you've seen them in action.

A quick word on washing (it's easier than you think)

The care routine is probably the most common reason people hesitate, and honestly? It doesn't deserve that reputation.

• Use toilet paper to remove any clots every time you go to the bathroom 

• Rinse in cold water after wearing

• Cold machine wash in a laundry bag

• Air dry only (no dryer)

• Skip the fabric softener and bleach

That's genuinely it. So easy it’ll become second nature within a cycle or two.

The bottom line

Choosing the right period underwear comes down to knowing your flow, thinking about your routine, and starting with what feels comfortable, not what feels like the most committed option.

Start with a light and a heavy pair. See how they fit into your life. Add from there.

Because when you get the right pair on the right day, your period gets just that little bit easier to manage. And honestly, that's the whole point.
