Main story: 

A conversation was had between the informant and myself. The informant can be known as MC and I will be known as MH. 

MC: There are these beads, they are called cycle beads. Think of it like a rosary. It is a necklace looking contraption. Based on the colors of the beads and the amount of them you can tell what days you will be fertile, infertile or menstruating. 

MH: And does this work? 

MC: I mean, it has been proven time and time again in modern medicine that things like these trackers are merely myths. If they actually worked it is most likely sheer luck. The only way to accurately prevent pregnancy is by either not having sex, or using contraceptives like condoms and IUDs. And predicting fertility is still something modern medicine cannot fully conceive. So I am not sure how much to believe about the beads, but they are interesting. 

Background: 

The informant studies public health and took a class on eastern medicine traditions. She found this one to be vastly interesting as women swear by it. But she knows through studying female reproductive health and sexual education that homeopathic methods like this notoriously do not work for most women. 

Context: 

The informant is a friend of mine and the conversation was held over facetime in a very casual setting as we talked about different approaches to health care. 

My thoughts: 

I am in a similar vein of belief with her. I do not know where I stand in believing in homeopathic methods. But they have often been used for centuries so there has to be levels of truth to them. Because anything that people dedicate that much time to has to have a certain level of importance for one reason or another. And there is some level of truth to the menstrual cycle counting with beads, some women do have very steady cycles that are predictable and they can use them to semi accurately predict fertility and pregnancy prevention. But most times I would more so believe that it is sheer luck as reproductive safety is pretty well documented that it cannot be tracked just through simple methods and birth control can only be achieved through methods like pills, IUDs or condoms.
