So in my family it is known to have terrible period cramps. I started my period earlier this year and they are already terrible. I pass out (literally) every time I start and I normally miss most of school during those 'fun' days. I am fine with taking birth control to help that. The only issue is I have one kidney. It is extremely hard to stay in school and play my sports during my period days. I don't know what to do. I know I should ask a doctor but I also want some personal opinions.
