Freiheit von der Pille

Jahrelang galt die Anti-Baby-Pille als Inbegriff weiblicher Selbstbestimmung. Heute sehen immer mehr Frauen, was sie auch ist: ein Medikament mit erheblichen Nebenwirkungen.

Viele wollen ohne Hormone verhüten. Aber wie geht das eigentlich?

Become Confident in Fertility Awareness for Preventing or Planning Pregnancy

The benefits of the Daysy are that it's not just a period or ovulation predictor like many fertility apps available today. The Daysy is actually a computer device that uses a proprietary system developed by their parent company Ladycomp and researched for over 25 years.

I first learned about the Daysy when Natalie Rechberg, the CEO of Daysy, joined my Women's Healing Arts Teacher Training. I was impressed with learning her story, that her father had invented the LadyComp and had grown this into an international company with decades of research in fertility awareness technology.

Could This Thermometer Overtake The Pill As Our Go-To Method of Contraception?

Technology, however, has rebooted natural family planning in recent years, making it far more reliable and user-friendly, and as a result, women are increasingly ditching the pill in favour of it. The name has even changed – most women who use it these days refer to it as the fertility awareness method or (FAM).

One popular tool among FAM devotees is the Daysy fertility tracker. It’s a highly sensitive thermometer that reads basal temperatures (the lowest body temperature attained during sleep) and then feeds the data into its tiny onboard computer that uses a complex algorithm to figure out if you might be fertile.

Does Fertility Awareness Method Work?

Before we dive in I want to say this — many people, including doctors, are quick to dismiss this method, claiming that women are too lazy or too easily confused by their own bodies to successfully use this method.

I disagree.

My experience is that women are motivated to understand their body and prevent pregnancy. And I would argue that the only person who truly understands your body is you. Instead of dismissing women, doctors should be teaching them how their body works and the signs and symptoms of healthy hormones.

As I mentioned in part 1 of my review I’m not generally interested in new technological devices. The “newest thing” is generally about making money by selling people technologies that they don’t need. After reading about Daysy and then trying it myself, I can honestly say that in my opinion Daysy is different. Daysy is designed to empower the consumers (women) by helping them to understand their own bodies and their own power.

Trying to Conceive? 7 High-Tech Fertility Monitors to Try

For at least the length of recorded history, humans have been attempting to plan and prevent pregnancy. From the practice of drinking lead in hopes of preventing pregnancy in ancient China, to dumping water on women to boost fertility in Hungary, there's always some wives' tale circulating about how women can harness their reproductive cycle.

The Pill and Your Mood

What if I told you that a product is available that can interfere with your hormones to the extent that your daily and monthly rhythms are no longer operational? And because you will no longer have functional brain to ovary signaling, you will likely avoid conceiving if you have sex during what would otherwise have been your 6 fertile days a month. Of course this product’s hormonal effects also leave you with the sense that everything is stable and predictable which is something like turning the white noise up so loud that you don’t hear your own baby crying.

The Pill May Be Wrecking Your Health

It has revolutionized women’s sexual and reproductive agency – but the birth control pill has a dark side. In light of a recent study linking the tiny tablet to depression, we explore the potential health fallout for a generation who came of age during a hormonal contraceptive boom.

The pill is linked to depression - and doctors can no longer ignore it

A newly published study from the University of Copenhagen has confirmed a link between hormonal contraceptives and depression. The largest of its kind, with one million Danish women between the ages of 15 and 34 tracked for a total of 13 years, it’s the kind of study that women such as me, who have experienced the side-effects of birth control-induced depression first hand, have been waiting for.

I’ve never been one to get all excited about the latest technological gadgets. It took me forever to get an iPhone and my laptop is six years old (and still works great by the way thank you!). So when I first heard about Daysy a year or so ago I wasn’t particularly interested.

Coming Off The Pill: What Are The Alternatives?

Are you and the pill over? You’re done with its crap - the weight gain, the hormonal spikes and the increased risk of breast cancer - and after a long-term relationship you’ve decided it’s time for you to seek out a change for your own good. Whatever. You’re over it. But what are you going to do now? Like a newly single lady, you need to assess your options and move on. You need to find out what is out there and see what you’ve been missing.

Natural Family Planning

Log into any apps account and type in the words period tracking and you’ll be faced with an abundance of apps – such as Daysy, Wink and ONDO - that will help you keep an eye on whether you’re meant to be ‘on’ or not. These, as well as a high-tech thermometer that promises to calculate your chances of getting pregnant are becoming the new fangled ways to keep on top of your cycle and potentially prevent an unwanted pregnancy. Harking back to forms of Natural Family Planning (or the ‘rhythm method’) can help track your fertility.

Good for you if: you’re up for keeping a daily record of your fertility signals (e.g. temperature, fluids coming from your cervix) and you have time to learn as it can take up to six menstrual cycles to be fully up to scratch with this method.
