Heavy Periods in Perimenopause: What to Know

Perimenopause guide

Quick answer

Periods can get heavier or longer in perimenopause, the years before menopause. Your hormones rise and fall, so your flow can change from month to month. Heavy bleeding is more common as you near menopause, but do not ignore it. See a doctor if bleeding is very heavy, lasts more than 7 days, or comes between periods.

Why are periods heavier in perimenopause?

Perimenopause is the time before menopause. Your hormones rise and fall. You may not release an egg every month.

So your periods can change. They may come closer together or further apart. Your flow may be light one month and heavy the next. You may skip some periods.

Heavy bleeding is more common as you get close to menopause.

Period underwear for perimenopause flooding

Some people call a sudden, heavy gush flooding. Perimenopause periods can also be hard to predict.

Kischt period underwear has three absorbent layers, made for heavier flow days. A moisture barrier helps stop leaks reaching your clothes. The gusset runs up toward the back, for extra coverage when you sit or lie down.

On your heaviest days, pair it with a pad, tampon or cup.
