This is an independent story from Sarah, a user who shared her personal experience using two fertility monitors to conceive with PCOS. At the end of this article, you'll also find an Editor's Note with expert context on why one tool may have worked better for her. But remember: personal experience and results may vary.
Why I Needed a Fertility Monitor With PCOS
My name is Sarah, and for years, trying to understand my own body felt like a full-time job with no instructions. Living with Polycystic Ovary Syndrome (PCOS) meant my cycles were anything but predictable, and they sometimes stretched as long as 35-60 days (which, if I’m honest, I didn’t always mind since it meant fewer periods!).
However, when my partner and I decided we were ready to start a family, the uncertainty of it all became really hard to carry. Each cycle brought more questions than answers, and the emotional toll started to build.
I knew I needed to do something, so I did what most people do when they want to plan a pregnancy: I went and bought generic ovulation strips at my local pharmacy.
But, to be completely honest, they left me feeling more confused than ever. The results weren’t really clear, and with my longer, irregular cycles, I never felt confident that I was actually testing at the right time or interpreting my results correctly.

This is ultimately what led me to research more advanced fertility monitors. I was tired of guessing, and I just wanted a clear path to pregnancy.
After some initial Googling, kegg was the first device that appealed to me. It seemed straightforward and non-invasive, using cervical mucus (instead of urine) to track fertility. In a way, it felt way less “clinical” than peeing on a strip. Plus, the whole testing process was super quick, and the kegg fertility monitor reviews were decent.
After placing my order, I was genuinely excited about finally having a plan and a tool that might give me some answers.
My Experience With kegg
When I first unboxed the kegg monitor, I felt pretty optimistic. The device itself felt really nice, and it was super easy to get everything set up. The daily testing routine was also easy to understand. All I had to do was insert the sensor for a couple of minutes each morning, and the app would give me a color-coded fertility score-low, medium, or high. I used it for three full cycles, waiting for that clear sign that I was ovulating.

But the simplicity that first appealed to me soon became a major source of frustration. I quickly realized that the probability-style feedback was not specific enough for my PCOS cycles. I kept waiting for something a bit more concrete, but the color codes often left me second-guessing myself and my cycle. What did a “medium” day actually mean for me? Was it the start of my fertile window, or just another hormonal fluctuation?
I found myself back in that familiar place of uncertainty, disappointment, and fear that I might never be able to plan a pregnancy with my partner.
When I Needed More Data
The emotional low point came after my second cycle with kegg. I still couldn’t really confirm ovulation. I didn’t know if I had missed my luteinizing hormone (LH) surge, or if it had even happened at all. On Cycle Day 21, the app showed “medium” fertility. On Cycle Day 27, I still didn’t know if I had ovulated or not. I felt stuck in a loop of hope and disappointment.
I soon realized that with PCOS, I don’t have the luxury of uncertainty. I needed to see what was actually going on with my body and hormones.
My Experience With Mira
So, I found myself back where I’d started; searching again, hoping to find a fertility tracker that could give me some actual answers. That’s when I stumbled on the Mira Hormone Monitor after going down a rabbit hole of PCOS forums.
I placed an order that night, and to be completely honest, switching to Mira felt like a real turning point for me. What drew me in was the ability to see my actual numeric hormone levels (not just probability scores that felt open to interpretation). The setup and testing process was just as straightforward as kegg, but the results felt a lot clearer and easier for me to interpret.

I remember the first time I saw my LH levels displayed as actual numbers. It was honestly such an “aha” moment. I watched them rise from 4.1 mIU/mL to 18.6 mIU/mL, and then peak at 32.4 mIU/mL. For the first time, I could clearly see my surge happening in real time. I also noticed my estrogen (E3G) was increasing before my LH peak, which was a sign my fertile window was opening. It actually turned out I was ovulating much later in my cycle than I’d always assumed.
From that point on, my mindset completely changed. I had faith in the process, and it felt like a huge weight off my shoulders.
What It Felt Like to Finally See My Hormones Clearly
Looking back, the biggest difference between kegg and Mira was in the way each one made me feel.
With kegg, I felt reactive, always waiting for a sign that never really came. But with Mira, I felt more proactive. Seeing my hormone curve and a clearer fertile window (even with my irregular cycles) was incredibly reassuring.

I will be honest about the cost: the Mira Wands are an ongoing expense (with kegg, there are no kegg test strips or wands to refill). But when I weighed that against months of uncertainty and the emotional toll of not knowing, the clarity was worth every penny. For the first time in my fertility journey, I felt in control. And that feeling was priceless.
Editor’s Note: Why Mira Worked For Sarah
Sarah’s experience really highlights an important difference between these two approaches to fertility tracking.
kegg is designed to measure changes in electrolytes in cervical mucus. It then uses this information to provide a general sense of when the fertile window might be approaching. For some, that level of insight is genuinely helpful for planning a pregnancy. Plus, it’s simple and non-invasive, so it’s easy to stick to as part of a daily routine (which is often half the battle with fertility tracking).
However, with PCOS, the body doesn’t always follow a predictable pattern, and those electrolyte changes don’t always clearly reflect what hormones are doing underneath. Hormonal shifts can be irregular, and an LH surge can be very easy to miss. This is why Mira’s approach of measuring actual hormone levels (particularly LH, E3G, and PdG) can often be valuable for people with PCOS like Sarah.
Yes, it’s more of a commitment in terms of cost and having to take a little more time for testing, but for many, that trade-off is worth it for the level of clarity and confidence it provides.

Stories like Sarah’s remind us that behind every data point is a deeply personal journey. As Mira CEO and Founder Sylvia Kang says, “We believe every woman, no matter how complicated or irregular their cycle is, deserves to know what’s going on with the hormones inside her body. Not only that, but they deserve to feel confident using that knowledge to make decisions about their reproductive health and fertility.”

Frequently Asked Questions About Mira vs kegg
Is kegg worth it?
Kegg can be a great fit if you have fairly regular cycles and want a basic way to estimate fertility. It gives you a general idea of when your fertile window might be, without needing test strips or much effort. For some people, that’s all they need. But if your cycles are irregular (for example, if you have PCOS), you might need something a bit more precise.
Does kegg work?
Yes, Kegg does work. It tracks electrolyte levels in cervical mucus, which can reflect what’s happening hormonally around ovulation. For many people, that’s helpful. But because it’s not measuring hormones directly, it may not be enough, especially if your cycle doesn’t follow a predictable pattern.
Where can I buy kegg test strips?
You actually don’t need any test strips with Kegg. It uses a reusable sensor instead, which is part of what makes it feel low-maintenance and easy to stick with.
What are the main differences between Mira vs kegg vs Inito?
The key difference comes down to how each device tracks fertility, and how precise the results are. Kegg uses cervical mucus to give a general idea of your fertile window.
Mira and Inito both track hormones, but they use very different technologies. Inito is based on traditional OPK-style, camera-read test strips, which can be influenced by lighting and phone quality. Mira uses fluorescent-based technology, which research suggests can offer higher sensitivity than color-based approaches.
