Only you know your flow and the stages of your cycle, so we’d recommend having a variety of absorbencies to match how much you’re bleeding from day to day. Here’s some useful information that tells you how much blood each absorbency holds as well as the tampon/pad equivalent.  Bikini Light - Holds up to 30ml blood/3 x mini tampons or 2 x light pads Bikini Moderate - Holds up to 70ml blood/7 x regular tampons or 2 x regular pads Short Light - Holds up to 35ml blood/3 x mini tampons or 2 x light pads Short Moderate - Holds up to 75ml blood/7 x regular tampons or 2 x regular pads Short Heavy - Holds up to 100ml blood/10 x heavy/super tampons or 3 x heavy pads Full Brief Moderate - Holds up to 80ml blood/8 x regular tampons or 2 x regular pads Full Brief Heavy - Holds up to 115ml blood/10 x heavy/super tampons or 3 x heavy pads
