And, I'm sorry, but I call bullshit. I use a menstrual cup and despite not having particularly heavy period I fill at least 3 a day for 3 days. No woman I've ever spoken to has only bed 3 tablespoons their entire period.
Did men measure this. Reading the comments I am not the only person who calls bullshit on this. AIBU?
