You have been matched to the Tampax Cup Size Heavy Flow. A wider diameter cup may be just the solution for leaks overnight. As you sleep your current cup seal may be lost or the cup has migrated into your vaginal fornix, allowing for leaks. The Tampax Cup Heavy Flow is also known to relieve bladder pressure for cup users who have experienced this from other cups. Despite the name "heavy flow" we match users to cups by size and not capacity for this result. The Tampax Cup Heavy Flow has an intimidating rim diameter but most users, myself included, find it a comfortable wear. We do recommend removing this cup at an angle to reduce the diameter.
