Jen Gunter Instagram – I get a lot of questions via DM, and it is rare for me to get one related to the menstrual cycle that isn’t found in my book, Blood. I address fertility awareness methods in detail so people can make educated choices about what works for them. There are different methods and they shouldn’t all be lumped in together. I believe in contraceptive choice, and for some people these are very good choices. For other people, they are not. I also have another chapter that discusses the dark side of apps that are used for menstrual tracking. There can be real privacy concerns with these apps as well as some of the apps for fertility awareness methods. Did you know in one study when a woman’s period came at a different time than the menstrual tracking app predicted, that she blamed herself (as in my period is wonky this month), but in reality the app was incorrect. If you want to know more, please check out Blood!
