Period Flooding: What It Is and What to Do
Heavy period guide
Quick answer
Period flooding is when blood comes out so fast that it soaks through your pad or tampon, sometimes onto your clothes or bed. It can be a sign of a heavy period. Change your protection, rinse stains in cold water, and talk to a doctor if it keeps happening.

What is period flooding?
Flooding is a sudden, heavy flow of blood. It can soak through a pad or tampon fast and leak onto your clothes or sheets. Doctors see it as a sign of heavy menstrual bleeding.
A small gush when you stand up is different. Blood can collect while you lie down, then come out when you get up. That is usually normal.
What to do if you flood
-
Stay calm
Head to a bathroom when you can. A sweater or jacket tied around your waist can cover a stain.
-
Change your protection
Put on a fresh pad, tampon or cup, and clean underwear if you have it.
-
Rinse stains in cold water
Rinse your clothes in cold water as soon as you can. Hot water can set a blood stain.
-
Write it down
Note the day, how fast you soaked through, and any clots. Share it with your doctor.
How to prepare for flooding days
- Pair a tampon or cup with period underwear as backup.
- Wear dark bottoms on your heaviest days.
- Keep a spare pair, pads or tampons, and wipes in your bag.
- Lay a dark towel under you in bed.
- Set a reminder to change before you get too full.
Backup for flooding days
Kischt period underwear has three absorbent layers and a moisture barrier. It is made to help stop leaks reaching your clothes. The protective area runs up toward the back, for extra coverage when you sit or lie down.
On flooding days, wear it with a tampon or cup. Change it when it feels damp, full or uncomfortable. Dark shades like Bordeaux show stains less.
