One Period Panty, Every Flow

The short answer: With Fabpad you don't need to choose an absorbency level. Every Fabpad period panty has the same absorbent core, made to handle light, medium and heavy days. What your flow changes is how often you change, not which pair you buy. So choose the style for coverage, clothes and time of day: Mid Waist for everyday wear, High Waist for tummy and back coverage, Period Boy Shorts for nights, skirts and dresses.

How to judge your flow: light, medium or heavy

Most people guess their flow from one bad day. A better way is to watch two cycles, because flow changes from day to day within the same period.

For context, the NHS says a typical period involves losing about 20 to 90 ml of blood, roughly 1 to 5 tablespoons, over 2 to 7 days. Bleeding is usually heaviest in the first 2 days. So almost everyone has a mix of heavier and lighter days, even if their period overall is "normal".

Simple signs of each kind of day

• Light day: a pad or liner looks only lightly marked when you change it, and you could easily go a full school or office day without worrying. Spotting at the start or end of your period counts here too.
• Medium day: a regular pad needs changing a few times a day, but you rarely leak and you do not think about your period much once you are dressed.
• Heavy day: you change often, you feel a gush when you stand up, you plan your day around toilet breaks, or you have leaked onto clothes or bedding before.

Keep a two-cycle flow note

On your phone, jot down three things for each day of your next two periods: light, medium or heavy; how many times you changed; and any leak, with the time it happened. Two cycles is usually enough to see your pattern, for example "day 1 and 2 heavy, day 3 medium, days 4 and 5 light". That pattern tells you how often to change on each day and when extra coverage or backup helps, far better than a guess.

If your notes show you changing every hour or two, needing two products at once, or bleeding for more than a week, those are NHS signs of heavy periods. Our guide on how much bleeding is too much explains what that means and when to get it checked.

One absorbency for every flow, three styles for coverage

Some brands sell separate light and heavy versions, so you guess your flow before buying. Fabpad keeps it simple: one absorbency for all flows. Every Fabpad reusable period panty has the same built-in multi-layer absorbent core and leak-resistant barrier, in soft cotton spandex, made to handle light, medium and heavy days alike. It can be worn for up to 8 hours depending on flow.

That changes how you choose. You are not picking a "light" or "heavy" pair. Any style works on any day of your period. Your flow decides how often you change, and the style decides coverage, comfort and what it looks like under your clothes:

• Mid Waist: sits at your natural waist and feels most like everyday underwear. Easy under jeans, trousers and fitted kurtas.
• High Waist: comes up higher, with more front-to-back coverage and tummy coverage. Popular for heavy days, nights and long hours of sitting.
• Period Boy Shorts: a longer leg and a wider absorbent zone, so the same core covers more area. Good for nights, skirts and dresses.

Alongside these, disposable period panties are worn once like underwear and are absorbent all around, which helps on travel days, long days out and after childbirth. If you are stuck between the first two styles, our side-by-side of high-waist vs mid-rise period panties compares them by clothes, cramps and fit.

How your flow changes your routine

Because the absorbency is the same in every pair, your flow pattern mainly tells you two things: how often to change, and when extra coverage or a backup product makes the day easier.

Light days and spotting

Any style works. Because your flow is low, a pair usually lasts comfortably through a school or office day, up to 8 hours depending on flow, so you are mainly choosing for comfort and what you are wearing. Most people reach for Mid Waist. Some people with very light days prefer a panty liner in regular underwear instead; both are fine.

Medium days

The same pair handles a medium day well; plan to change around lunchtime. If you sit for long stretches, for example in a long lecture or a back-to-back meeting day, a High Waist pair gives more coverage at the back, where flow tends to collect when you are seated.

Heavy days

The absorbent core is the same one you wore on day 4. What changes is timing: expect to change sooner than 8 hours on your heaviest day. Coverage helps too. High Waist and Period Boy Shorts give flow more room before it reaches an edge, and a higher waistband helps keep the gusset in place as you move. Our guide to period panties for heavy flow goes into heavy-day timing, leaks and getting through school and work in detail.

Which style for which time of day and activity

Daytime at college or the office

Choose by clothes first, since every style has the same absorbency. Mid Waist sits neatly under jeans and trousers. High Waist sits comfortably under salwars, leggings, sarees and kurtas, and the tummy coverage is welcome if you get cramps or bloating. If you can only change once in a long day, lean towards the higher-coverage style.

Nights

Lying down lets flow travel towards the back, and turning over can shift things. High Waist or Period Boy Shorts are the usual choice, with boy shorts suiting restless sleepers. Put on a fresh pair just before bed. For sleeping positions and a full bedtime routine, see period panties for sleep.

Sport, yoga and dance

Movement matters more than flow here. Boy shorts stay put during stretches and stop thighs rubbing under a skirt or dance costume. A High Waist pair works well under leggings. For swimming, a cup or tampon works better.

Travel and long days out

On a long train or bus journey, a wedding or a day of sightseeing, the question is how often you can change in a clean toilet. If the answer is "rarely", consider a disposable period panty, or start in a fresh High Waist pair with a pad on top and carry a spare.

Postpartum, teens and changing cycles

After childbirth

Bleeding after birth, called lochia, is heavy at first and lasts a few weeks, getting lighter and browner over time. The NHS advises super-absorbent pads at first and no tampons until after your 6-week postnatal check. Disposable period panties are useful in the early days, and High Waist pairs give gentle tummy coverage as bleeding settles. Tell your midwife or doctor if you pass large clots, and get urgent help for sudden, very heavy bleeding.

Teenagers

The Period Panty for Teens has a 5-layer absorbent core and is sized by age, from 10 to 12 years up to 18 to 20 years, which keeps things simple. On a heavy school day, a pad on top gives extra confidence.

When your flow changes

Flow shifts with age, after pregnancy, with PCOS and before menopause. Re-check your flow note every few months.

When to add a pad, cup or tampon as backup

Using a period panty with another product is not a sign it is failing. NHS inform notes that some people use period pants as their only product, while others combine them with something else on heavy days to feel more confident.

• Panty plus a pad: handy on your heaviest morning, on long journeys, and for your first cycle while you learn your timing. The panty catches anything at the edges.
• Panty plus a cup or tampon: the cup or tampon does the main work and the panty catches small leaks. Useful on long workdays or during sport. Follow the usual guidance on changing times for tampons and cups.

If you want a starting set that covers all of these, the Hybrid Cycle Kit includes 2 period panties plus disposable period panties, cotton pads and liners.

One caution: if you regularly need two products at once just to get through an ordinary day, that is itself a sign of heavy periods, and it is worth mentioning to a doctor.

Decision table: match your day and plans to a style

Every style has the same absorbency, so this table is about coverage, changing and backup. Adjust it after a cycle or two.

Putting together your first set

Take Priya, who works in an office and wears trousers. Her notes show two heavy days, two medium days and one light day, with heavy nights on days one and two. Since every Fabpad pair has the same absorbency, she does not need light and heavy versions. She picks by coverage and clothes instead: High Waist pairs for the long, heavy office days when she sits for hours, a pair of boy shorts for her heaviest nights, and Mid Waist under her trousers for the rest of the week. On her heavy days she simply changes more often.

How many of each you need depends on how often you can wash and how quickly pairs dry, especially in the monsoon. Our guide on how many period panties you need works through the numbers. On fabpad.in, buying more pairs gives a bigger discount, so mixing styles in one order also works out cheaper per pair.

Before ordering, check your size on the product page. Sizing can differ slightly between styles, and a snug fit at the legs matters as much as the style itself. Our period panty size chart explains how to measure. Fabpad suggests testing a new pair at home first to learn how long it lasts on your flow before wearing it out.

Signs you need a different style

After a cycle, look back at any leaks or discomfort. Some point to the style, not the product:

• Leaks at the back after sitting or sleeping: you probably need more coverage. Move up from Mid Waist to High Waist, or to boy shorts at night.
• The pair feels full well before you can change: your day is heavier than the plan. A different style will not add absorbency, so change sooner, or add a pad, cup or tampon for those hours.
• Thighs rubbing under skirts or dresses: boy shorts help.

Leaks at the leg openings, rolling waistbands and bunching are usually about size or fit rather than style. Our guide to period panty rolling, bunching or leaking goes through each cause and fix.

When your flow is a reason to see a doctor

Choosing the right underwear makes heavy days easier, but it does not treat whatever is causing heavy bleeding. Heavy periods have many possible causes, and a doctor can look into them and suggest treatment.

See a doctor if

• you change a pad or period panty every one to two hours, or need two products at once
• your period lasts longer than a week
• you pass clots bigger than about 2.5 cm, roughly the size of a ₹10 coin
• you often bleed through to clothes or bedding
• heavy periods stop you from going to school, work or doing everyday things
• you often feel tired or short of breath, or have severe period pain
• you bleed between periods or after sex

Get urgent help if

Call 112 or 108, or go to the nearest hospital emergency department, if you are bleeding very heavily and feel faint or dizzy, if you have sudden heavy bleeding after giving birth, or if you might be pregnant and have heavy bleeding or severe tummy pain.

Frequently asked questions

Do I need different period panties for light and heavy days? Not with Fabpad. Every Fabpad period panty has the same absorbency, made for light, medium and heavy days. You simply change more often on heavier days.

Which period underwear is good for a heavy flow? Any Fabpad style handles heavy days. High Waist and Period Boy Shorts give the most coverage, which helps on heavy days and nights. Change sooner than you would on a medium day, and add a pad for your heaviest hours if you need to.

Is Mid Waist enough for a heavy flow? Yes. It has the same absorbent core as the other styles. If you sit for long hours or have leaked at the back before, the extra coverage of High Waist can help on those days.

Can I wear a period panty with a menstrual cup or tampon? Yes. The cup or tampon does the main work and the panty catches small leaks. It is a popular combination for long workdays and sport.

What should I choose for my first period panty? Pick the style that matches your most stressful time. If that is nights or heavy mornings, start with High Waist. If you mostly want everyday comfort, start with Mid Waist.
