Why are we taught so little about something that happens every single month for decades of our lives?
In this episode of Fertility Café, Eloise Drane sits down with fertility awareness educator and author Lisa Hendrickson-Jack to unpack one of the most overlooked truths in women’s health: the menstrual cycle is not just about getting pregnant. It is a vital sign.
From heavy periods and birth control prescriptions in her teens to becoming a pioneer in fertility awareness education and podcasting, Lisa shares how charting her cycle transformed her understanding of her body and ultimately her career.
This conversation goes far beyond basic sex education. It breaks down what is actually happening during your cycle, how ovulation impacts overall health, what hormonal birth control really does to the body, and why so many women feel confused or dismissed when something feels “off.”
If you have ever been told your symptoms are normal when they do not feel normal…
If you have ever come off birth control and wondered why your body felt different…
If you want to better understand what your cycle is actually telling you…
This episode is for you.
