"What on earth is that?!", you might be thinking - and I don't blame you, as a few months ago I would have thought the same myself! This little gadget is a fertility monitor that you use every morning to take your temperature, and it then shows your current fertility status. Your basal body temperature rises slighty after you ovulate, so after using Daysy for a few months she will have an accurate knowledge of your cycle, and based on your temperature in the morning she will then give you either a green light (meaning you are infertile) or a red light (meaning that you are fertile) for that day. She might also give you a yellow light, which means she is either still learning about your cycle (I am getting all yellow lights at the minute) or there has been an unexpected temperature fluctuation, so you should abstain or use a barrier method. Of course, if you are planning to get pregnant then the Daysy is also a very useful tool for that, too!
If you are a natural sceptic like me, you may be wondering just how accurate this will be. Basically, it is a high-tech version of the Fertility Awareness Method (NOT the same as the Rhythm Method!) in which you chart your basal body temperature, plus other signs such as cervical fluid, to gauge your fertile window. However Daysy does your temperature charting for you; there is also a DaysyView app you can download for your mobile and you can sync your device with that. According to the Daysy website, it is 99.3% accurate. This is around the same rate as the pill and the implant, which are both 99% effective, if used correctly in the case of the pill.
I will report back with my thoughts and findings about Daysy in a few months, after I have had a few cycles of use. If it is something you might be interested in, I highly recommend doing plenty of research, like I did, and reading a book called Taking Charge of Your Fertility by Toni Weschler which should, quite frankly, be a must read for anyone with a uterus! At the end of the day it's your body and you have to do what you're happy with. Right now for me, that is being as free from artificial hormones and chemicals as possible!
Have you tried FAM or a fertility monitor before, or is it something you would consider?
