period support

Disposable menstrual discs and many period underwear styles advertise protection for up to about 12 hours. Heating patches that relieve cramps typically provide several hours of warmth, commonly up to about 8 hours.

Absorbency is usually reported as tampon equivalents or in milliliters. For example, some discs are listed at about 60 mL (roughly 5+ super tampons), some period underwear show absorbency in tampon equivalents (up to 12 regular tampons), and certain briefs state they replace multiple pads or tampons.

Products typically provide a full size chart with hip measurements and corresponding US pant sizes, plus fabric blend, rise (low/medium/high), and pant-size ranges to help match fit. Product bullets often list intended fit (women’s sizing) and materials to guide selection.

Pinch the disc, insert it down and back toward the tailbone, then tuck the front rim up behind the pubic bone. Many discs are suction-free for easier removal, and some designs can self-empty during urination.

Follow the product care instructions—machine wash cold or hand wash, then line dry or lay flat to dry. Some products note a recommended replacement after about 30 washes.
