- + What are the best heavy flow period panties? 

We have the best heavy flow period panties on the market. Heavy flow panties should offer superior hygienic protection while keeping you feeling fresh, clean, and dry. Louloucup offers various models for heavy flows in bright colors, classic black, fun prints, or plain.
One of Louloucup's priorities is to cater to as many women and teenagers as possible. That's why our models are, for the most part, available from size XS to XXXL.  

- + What is a heavy flow? 

A menstrual flowis considered heavy when it is between 50 and 70 ml.

- + What is very heavy or hemorrhagic flow? 

A menstrual flow is considered very heavy when it exceeds 70 ml. It is often due to wearing a intrauterine device like a copper IUD. This non-hormonal contraception often causes intense bleeding that tends to subside over time.  

- + When are heavy flow panties useful? 
  • for absorbing all of your period blood
  • to manage heavy bleeding caused by a Copper IUD
  • to manage lochia and post partum
  • to manage heavy flows during night.
  • to manage a flow during an intense day (travel, work, etc.)

A whole day.
The Louloucup period panties are designed to be worn for many hours. The goal is to free you from your restrictions and to forget them.
