Accurate thanks to smart internal algorithm
Daysy contains very precise sensor technology for measuring BBT (basal body temperature). Measure immediately in the morning after you wake up.
Your measurement is compared by the internal algorithm with fixed data from 5 million menstrual cycles of 500,000 women. Daysy also learns from your previous cycles. For example, if you ovulate later than normal, your period may also be later. In short, the distribution between fertile and infertile days is carefully determined every day.
Do you not wish to have children at the moment? Then you can use a barrier method such as condoms during fertile days.

With Daysy I measure my basal body temperature every morning and track my cycle and fertility. I currently have no desire to have children, so it is super important for me that it is reliable and that it offers me insights into my fertility. 😊

S*x without feelings of depression, weight gain, nausea, migraines, bleeding in between and a low libido sounds quite interesting, right? 🤪 I thought so too. That's why I stopped taking hormonal birth control. I wanted to know who I really was without artificial hormones...

🌡 Daysy. Recently I posted a story and my inbox exploded. I stopped 2 months ago, initially as a last resort for those enormous stomach aches and also because I've been on those damn hormones for too many years. I was a bit fed up with it and I noticed that I just haven't really felt comfortable in my body since then.

Since the switch, I sleep much better, am less stressed and generally feel happier. Because I don't want children for a few years, I now use Daysy to track my cycle.

I feel so good about myself!✨This of course has several reasons, but one of them is that I no longer use contraception. I was done with all the hormones and wanted to get back in touch with my own body!

I can only advise other women to do research and look beyond the standard hormonal contraception that the doctor prescribes... there is more possible.
