John Guillebaud, a professor of reproductive health at University College London, said that patients have described the cramping pain experienced as a result of menstruation as "almost as bad as having a heart attack."

While some may be shocked by the idea that the levels of pain many women experience due to dysmenorrhea (the fancy medical term for painful periods) reach these heights, uterus-havers worldwide couldn't even act surprised, since this isn't news to any of us. There is often a lack of understanding and research where women's health is concerned.

Never underestimate period pain women suffering.
