I wondered about this situation and then Ma Louloute explained to me!
I find myself losing more than 80 ml of menstrual blood a day. That is, a little less than the amount of shower gel allowed on the plane. So I have to change hygienic protection every 2 hours. And then my rules last more than seven days.
I asked myself questions about this, but thanks to Ma Louloute’s website, I understood that I had to go to a doctor.
