People who feel ill at periods or menstruating in general shouldn't feel shame, we need to discuss why it is a woman or girl should ever have negative feelings towards a natural bodily function/process.
I started mine just before I turned 10, I used to get horrendous pain that I needed time off school for so yes I didn't enjoy it, I saw a specialist at 11 and of-course it was a man, and before they even bothered to look into the history properly, they tried to insinuate that my periods might have dissapeared because I was pregnant, no compassion or anything, just very rudely kept asking if I'd been having sex, really? at 11? is it really called sex at that age? surely some sort of abuse has happened if that was the case, my answer was no but they still insisted a nurse did an examination, I felt like a criminal not a child with severe menstrual problems .
They can fuck off with their badly veiled misogynistic language and their homogenizing and censoring of women's bodies. Periods happen, they're messy and probably painful, they are an important female experience which for many women around the world causes hardship and fucks up their education. Anybody that needs it explaining or finds it offensive should seek psychological help ,sorry I'm a 'terf' so I obviously mean conversion therapy.
