Dr. Jen Gunter fights myths and fear-mongering with real science, inclusive facts, and shame-free advice on the topic that impacts more than 72 million Americans every month: menstruation. Most women, transgender, and non-binary people who menstruate can expect to have hundreds of periods in a lifetime. So why is real information so hard to find? Despite the significance of menstruation, most education focuses on either increasing the chances of pregnancy or preventing it. Those who menstruate deserve to know more about their bodies than just what happens in service to reproduction. At a time when charlatans, politicians, and social media are succeeding in propagating damaging disinformation with real and devastating consequences, Dr. Gunter provides the antidote with science, myth busting, and no-nonsense facts.
