Endometriosis is often underdiagnosed because of this and even other problems that may not even have to do with the uterus like UTI which can hurt in a similar way you'll get the "it's just your period". There are so many bad doctors like that even female doctors because the truth is that the female body hasn't been studied as much as the male body so there's still a lot that they're not sure of.aq And it's not just women, because skin ailments have been studied mostly in white people the conditions are described like what they look like in fair skin and they may look completely different in other complexions. Good for you for finding that pill!! I feel bad for 11yo you for having to go through all that pain. Women and girls deserve better treatment
