6 tips for couples facing fertility issues

It is possible to get pregnant only during a few days every cycle. That is why it important for couples to educate themselves about their most fertile days as every woman has her own unique cycle which is controlled by their hormone levels. Therefore, using fertility monitors which identify up to 6 fertile days of your cycle can help you a lot.

The Fertility Awareness Method.

Ever heard of the Fertility Awareness Method? No, it is not the Rhythm Method, an ineffective method of contraception based on an average of past cycle lengths with no observations of impending ovulation in the current cycle. It’s also not the pull out (or withdrawal) method, although that is a real contraceptive practice—and way better than using nothing at all, admonishes Planned Parenthood. And, it’s absolutely not a guessing game when, in the heat of the moment, you quickly calculate how far you are from 14 days since your last period and decide that just this time, it’ll be fine. Fertility Awareness Methods, or FAMs, are actually a set of scientifically valid ways of tracking your ovulation to determine when during the month you’re fertile, and when you’re not, so that you can use barrier protection (or abstain) only on the days when it matters, and just go for it the rest of the month.

New Research: Birth Control Pill, Depression and Autoimmunity

The evidence that our brain health depends on our immune systems and hormones continues to pile up. Given this interconnectedness, dubbed psychoneuroimmunology, it makes sense that interfering with our delicate hormonal balance can influence psychiatric diagnoses like depression.[1] Yet over 100 million American women are prescribed synthetic hormones in the form of oral contraceptives (“the pill”), despite the fact that women on the pill have a higher risk of being diagnosed with depression (among other diagnoses) than those not taking oral contraceptives.[2],[3],[4]

Non-Hormonal Alternatives to the Birth Control Pill

There are many reasons you might be looking for a non-hormonal alternative to the birth control pill. Perhaps you, like many women, are experiencing symptoms associated with the pill like depression, nausea, low sex drive or headaches. Or perhaps you’ve got a sneaking suspicion that your adrenal and thyroid issues may be linked to the pill.

Meet Daysy, a Hormone-Free Contraceptive Thermometer

Since I was 17 I’ve been on birth control pills. I had no idea how disconnected I was from my body, but at the time, avoiding acne and pregnancy seemed like a pretty good deal to me. I was not aware of how the pill was affecting my body or my mood. I always thought I was, by nature, a moody person due to my periods, but I soon realized how wrong I was once I stopped taking birth control.

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.

I'm Ditching Hormonal Birth Control, and How You Can Too

I've been on and off birth control since my late teen years, and I've always been subject to the negative side-effects. For the longest time, I thought this was my only choice for birth control. I was never informed that my cycles could actually be tracked and I could go hormone-free.

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.

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.

Discovering a Natural Birth Control Method I Actually Trust

Two years ago, when I met my current boyfriend, and knew it was going to be more than a fling, we had a serious conversation about birth control… together (a very new experience for me). I told him that I had serious reservations about getting back on the pill, primarily because at that point in my life, after a serious bout of Lyme’s Disease and subsequent thyroid issues that put my hormones totally out of whack, I was just trying to get my body back to neutral. In truth, there was also something liberating about feeling that my body and my cycle had, for the first time since I was 15, been occurring naturally for several years without any influence from synthetic chemicals or hormones.

Birth Control: You Have Another Choice

Now I had looked into a few Pinterest articles that talked about women learning their menstrual cycle and learning days they are fertile and not. While this sounded like a great (and free) option, I didn’t feel comfortable trusting a few websites, and myself, to tell me what days I wasn’t going to get pregnant. Nope, do not want to be pregnant right now. All hope was lost, but we felt like there was still something missing…another, better option. Then I stumbled upon a Facebook article about a birth control method called Daysy.
