There's a heavy day in most cycles, the one where you plan your route around bathrooms and wear the dark jeans. This article is about getting through that day. But before the tips, one line we mean: heavy bleeding is not something to push through with hacks. ACOG says it plainly: heavy menstrual bleeding is very common, about one third of women seek treatment for it, and it "is not normal." So, first: where does your heavy day sit on that scale?
What counts as a heavy period
The NHS says you may have heavy periods if you need to change your pad or tampon every 1 to 2 hours or empty a cup more often than recommended, need two products together (a pad and a tampon), have periods lasting more than 7 days, pass clots larger than about 2.5 cm (a 10p coin, close to a US quarter), or bleed through to your clothes or bedding. ACOG's list matches: bleeding that soaks through one or more tampons or pads every hour for several hours in a row, needing more than one pad at a time, needing to change during the night, clots as big as a quarter or larger, and bleeding that lasts more than 7 days. Cleveland Clinic puts the volume at more than 5 tablespoons over a period, against a typical 2 to 3. If any of that is your normal, the tips below are for getting to the appointment comfortably, not instead of it.
Heavy period tips for getting through the day
1. Count, don't guess. Products per day, hours between changes, clots and their size, days of bleeding. Two cycles of notes turns "it's heavy" into numbers, and numbers are what a doctor can act on.
2. Layer, and notice if you always have to. Period underwear under a pad, or a pad behind a tampon, on the heaviest day. The NHS lists needing two products together as a sign of heavy periods, so if this is every cycle, that goes in the notes too.
3. Build the heavy-day kit. Double the products you'd pack for a normal day, spare underwear, a zip bag, and the dark layer. Our period kit checklist has the full list; the heavy-day version is that list times two.
4. Ask about NSAIDs, for flow as well as pain. ACOG notes that NSAIDs such as ibuprofen "also may help control heavy bleeding and relieve menstrual cramps." Same rules as always: at the first sign, with food, and not if you have a bleeding disorder or any of the other exclusions on ACOG's list.
5. Sit down when you're lightheaded. Feeling faint, dizzy or short of breath is not a heavy day, it's a red flag; Cleveland Clinic says bleeding through two or more pads or tampons an hour for two to three hours in a row is a reason to seek emergency care. Stop, sit, and if it doesn't pass, get help.
Heavy period tips for iron, food and the night
6. Take iron seriously. The NIH names women with heavy menstrual bleeding as one of the groups most likely to have inadequate iron: women with menorrhagia lose significantly more iron per cycle than women with normal bleeding, and the RDA for women aged 19 to 50 is 18 mg a day.
7. Eat the iron foods, with something sour. From the NIH table: fortified breakfast cereal at 18 mg a serving, white beans 8 mg a cup, beef liver 5 mg per 3 ounces, lentils, cooked spinach and firm tofu at 3 mg per half cup, and 45 to 69% dark chocolate at 2 mg an ounce. Vitamin C makes the plant kind easier to absorb, so squeeze the lemon over the lentils.
8. Don't self-prescribe iron pills. Get the blood test. The NHS says blood tests to check for iron deficiency anaemia are part of assessing heavy periods. Too much iron is its own problem, so this one goes through a doctor.
9. Make the night plan. Overnight pad plus period underwear, a dark towel on the sheet. ACOG lists needing to change during the night as one of the signs of heavy bleeding, so if you're setting an alarm to change, that goes in the notes as well.
10. Warm food, salt, water. Heavy days usually come with cramps, and the cramp basics still apply: heat, hydration (Cleveland Clinic's gynecologists say dehydration can make cramps worse), and something to eat. Our foods that ease period cramps list is the shopping version.
What the doctor can do that a hack can't
ACOG's page lists the treatments: tranexamic acid, a prescription tablet taken each month at the start of the period; hormonal methods; NSAIDs; and for causes like fibroids or polyps, treatment for the cause. Mayo Clinic adds the reason it matters: heavy bleeding can leave you tired or short of breath from blood loss. The point: heavy periods are treatable, and the appointment is where that happens. Our honest limitation: several of us spent a decade assuming our heavy day was just what periods were, because everyone around us said so. Nobody counted. Count.
We make a chocolate, and we'll be clear about what it's for. Girl Chocolate is a dark chocolate bar for the days around your period, with magnesium and other functional ingredients, sold as a pouch of eight bars for one cycle. Supports PMS relief*. It does nothing for how much you bleed and we'd never claim it did. Heavy days are still cramp days, though, and that's where it sits in our own bags. If you're curious, here's the bar.

When to talk to a doctor
Heavy bleeding has real red flags. Book an appointment, or seek urgent care for the first one, if you have any of these:
- Soaking through a pad or tampon every hour for several hours in a row (two or more an hour for two to three hours is an emergency)
- Passing clots larger than a quarter
- Bleeding for longer than 7 days, or bleeding between periods or after sex
- Feeling faint, dizzy or short of breath, pain that stops daily life, or pain with a fever
