Period cramps

Can we get a petition going so that we can get out of school/ work ect. For periods. As I lay in my bed knowing I have a 10am class I think to my self if you move just a little all the blood will rush out and the horrible cramps will start. So I just sit still in my bed and pray that my professor cancels or something but they never doooooooooooooooooooooooooo!!!

Venting I’m just venting at this point
