The best overnight pads for heavy flow check a few non-negotiable boxes: maximum absorbency, extended back coverage for lying down, leak-proof side barriers, wings that hold position through hours of movement, and a topsheet that stays gentle even at high absorbency.
A 100% organic cotton topsheet, plus an elemental chlorine-free wood pulp absorbent core, gives you absorbency without fragrance or dyes sitting on sensitive skin overnight. Some overnight pads also feature absorbent channels that draw liquid toward the center of the pad, reducing the risk of leaks on the sides.
Overnight pads are designed for up to 10 hours of wear, which is longer than a daytime pad. Pads should be changed every few hours during the day, so overnight versions are sized and engineered specifically for the longer stretch.
Cora's organic cotton topsheet overnight pads with wings deliver maximum absorbency, leak-proof side barriers, extended back coverage, and the same fragrance-free, dye-free, elemental chlorine-free standards as the rest of the lineup. Our extra heavy overnight pads offer even more back coverage and double wings to prevent back spills and shifting.
When Should You Talk to a Doctor About Heavy Flow?
A lot of people have heavier days during their cycle, and that's normal. However, bleeding that soaks through one or more pads or tampons every hour for several hours in a row, lasts more than seven days, or includes blood clots the size of a quarter (or larger) can be a sign of heavy menstrual bleeding that's worth bringing up with your OB-GYN.
Underlying causes of a heavy menstrual flow can include hormonal shifts, fibroids, bleeding disorders, or other conditions that have treatment options. Overnight pads can manage heavy flow comfortably, but they aren't a replacement for a conversation with a doctor if the flow itself feels unusually heavy.
