How I Compared Mira vs Proov While TTC and What Helped Me Feel More Confident

This is an independent story from Jessica, a woman who shared her personal experience using two fertility monitoring tools to conceive. 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.

My name is Jessica, and I'm a 29-year-old high school teacher from Denver, Colorado.

When my partner and I decided we were ready to start a family, I honestly thought getting pregnant would be easy. Like a lot of people, I assumed it would happen within a few months. But as one cycle turned into another, I found myself getting more and more discouraged.

At first, I tried not to worry about it. My friends and family kept reminding me that conception can take time, and I really wanted to stay positive. 

However, after several months of negative pregnancy tests and endless ovulation predictor kits (OPKs), I started wondering if there was something more going on. 

That's when I scheduled an appointment with my doctor. And after some routine testing, we discovered that my luteinizing hormone (LH) levels were lower than expected. And while this didn't answer all of my questions, it was the first clue that my hormones might be playing a role in the challenges we were facing.

Why I Started Looking Into Hormone Tracking

I knew from that doctor's appointment that my LH levels were low. But what I didn't know was if my lower-than-average LH levels were causing me to miss my fertile window each month, or if I was even ovulating when I thought I was.

From that point on, I became determined to learn more about my hormones. More than anything, I wanted information I could use to have more meaningful conversations with my partner and my doctor.

That's what ultimately led me to explore at-home hormone tracking. Because if my hormones were influencing my chances of conceiving, I wanted a way to see what exactly they were doing instead of simply hoping for the best each cycle. 

My Experience Using Proov

After researching different fertility tracking tools and devices, I decided to try Proov. I had read some positive Proov fertility monitor reviews, I knew where to buy Proov test strips, and it honestly seemed like a good starting point. I was hopeful that Proov would finally provide me with some clarity after months of feeling confused about what my body was doing.

What I Liked at First

At first, Proov felt like exactly the kind of support I needed. The Proov test strip refills were easy to order, and I liked the idea of being able to track my hormones at home.

I also appreciated having something tangible to rely on. The test strips were straightforward (very similar to a basic pregnancy or OPK test strip), and the app gave me a place to log my results. 

The whole setup made hormone tracking feel easy and accessible, and it didn't take me much time at all to understand how to interpret my results. Seeing my cycle information laid out in such a structured way was genuinely reassuring. And for the first time, I felt like I had something tangible that supported what my doctor had told me about my low LH levels.

The Problems I Started Noticing

As I continued using Proov, though, I started running into some frustrations that I hadn't expected when I first began tracking.

One of the biggest challenges for me was the testing process itself. Because the system relies on using your phone's camera to read the test strips, I found myself paying a lot of attention to things like lighting, shadows, and positioning. Most days, everything worked fine, but every now and then I'd get a result that didn't seem quite right or a test that needed to be repeated.

At first, I assumed I was doing something wrong. Maybe the lighting in my bathroom wasn't ideal, or maybe I wasn't holding my phone at the right angle. But after it happened multiple times, I became a bit frustrated. 

There were mornings when I would complete a test, only to question whether the result was accurate. If you've ever been on a TTC journey, you'll know that timing is crucial, and I didn't always have the luxury of waiting another day to retest. 

All in all, the more uncertainty I felt about individual readings, the harder it became to trust the overall picture. 

Why I Decided to Switch to Mira 

Eventually, I realized that the inconsistent readings with Proov were adding to my stress, rather than reducing it, and I finally came to the conclusion that I needed to try something different. 

That's when I started researching other options and came across Mira. I had seen the name mentioned in fertility forums and online TTC communities before, but this time I took a closer look.

Looking for Better Cycle Insights

What immediately stood out to me was that Mira uses a dedicated analyzer to read each test wand internally, rather than relying on a smartphone camera. That might seem like a small difference, but after months and months of worrying about whether or not a result had been read correctly, it felt like something I might actually be able to rely on.

At that point in my TTC journey, reliability mattered just as much as the data itself. I didn't want to spend time wondering if poor lighting or an imperfect scan had affected my results. I wanted to feel confident that what I was seeing reflected what was actually happening in my body.

More than anything, I was looking for consistency. Trying to conceive can already feel emotionally overwhelming, and I wanted a tracking system that would reduce uncertainty rather than add to it. 

If I was going to make decisions based on my hormone data, I needed to be able to trust it.

My Experience With Mira

To be completely honest, switching to Mira felt like a huge relief. 

The testing process was just as straightforward as Proov, but the experience felt much more consistent for me. Instead of worrying about whether a result had been affected by lighting or the way I scanned a strip, I could simply run the test and focus on understanding my cycle.

As the weeks went by, I started to see a much clearer picture of what was happening hormonally. The patterns I was seeing were similar to what my fertility doctor had observed, and that gave me a real sense of confidence. 

For the first time, I felt like I could follow my hormone changes throughout my cycle. I could see my estradiol levels rising before my LH increased (even though they were low), which really helped me to relax and trust my body during my fertile window. 

What Changed After I Started Understanding My Hormones Better

Looking back, the biggest change wasn't really about the data; it was how I felt about myself and the entire TTC process. 

Before, every cycle seemed to bring more questions than answers. I was constantly wondering whether I was ovulating, whether I was timing things correctly, and whether my low LH levels were affecting my chances of conceiving. 

However, once I started seeing my hormone patterns more clearly, it felt like a cloud of stress had been lifted. My cycle finally made sense, and for my partner and me, it meant everything. 

Editor's Note: Why Mira Worked Better for Jessica

Jessica's experience highlights how different fertility tracking technologies can lead to very different user experiences.

Proov relies on a smartphone camera to interpret the test strips. For many people, this approach provides useful hormone insights. 

However, Jessica was specifically trying to understand her fertility after learning that her LH levels were lower than expected. In that situation, having confidence in each test result became especially important. Over time, she found herself worrying about whether factors like lighting, shadows, or the scanning process could affect her readings, which made it harder for her to fully trust the data.

Mira, on the other hand, uses a calibrated optical analyzer with embedded quality control and FluoMapping™ Technology to read each wand internally. While that may sound like a small technical difference, it was meaningful for Jessica because it removed some of the variables she had been concerned about when testing.

Studies have suggested that fluorescent detection methods can offer higher sensitivity than traditional color-based approaches. So for someone like Jessica, who was tracking relatively low LH levels and looking for a clearer understanding of her fertile window, that additional sensitivity may have helped her feel more confident in the results she was seeing.

Of course, everyone is different, and no fertility monitor is universally best for everyone. The right choice depends on your goals, your budget, and the level of detail you're looking for. 

Comparison Table: Proov vs Mira

If you're actively trying to conceive (TTC) and weighing up your options for fertility tools, here's a simple breakdown of how Mira and Proov compare and what you can expect from each.

Stories like Jessica's remind us that when you're trying to conceive, having confidence in the information you're using can make a meaningful difference in how you approach each cycle.

As Mira CEO and Founder Sylvia Kang says, "Having hormone data is important, but being able to trust that data is equally important. We believe women deserve tools that help them feel confident in the information they're using to make decisions about their health."

Frequently Asked Questions About Mira vs Proov Fertility Monitoring

How does Proov work?

Proov is an at-home hormone tracking system that uses urine test strips to measure fertility-related hormones throughout your cycle. After testing, you use the Proov app to scan and interpret your results, which can help you better understand patterns related to ovulation and fertility.

What is the Proov monitor?

Proov is not technically a fertility monitor in the same way that devices like Mira are. Instead, it's a hormone testing system that uses urine test strips and a smartphone app. 

Many people refer to Proov as a "fertility monitor" because it helps track ovulation and hormone patterns. However, unlike dedicated fertility monitors that use a reusable analyzer to process tests internally, Proov relies on test strips and smartphone-based interpretation.  

Does Mira track different hormones than Proov?

Both Mira and Proov measure several hormones that play an important role in fertility. Depending on the kit, both can track LH, FSH, and progesterone and estrogen metabolites in urine.

One key difference is that Mira tracks E3G (estrone-3-glucuronide), while Proov measures E1G (estrone-1-glucuronide). Both are estrogen metabolites that can provide insight into hormonal changes throughout the cycle, but they are different biomarkers and may offer slightly different perspectives on estrogen activity.

What is the difference between Mira vs Proov vs Kegg? 

The biggest difference is how each product gathers information about fertility.

• Mira measures hormone levels directly from urine samples using a dedicated Analyzer.

• Proov also measures hormones through urine testing, but relies on smartphone-assisted test strip interpretation. 

• kegg takes a completely different approach by monitoring changes in cervical mucus electrolytes to estimate fertility patterns.

None of these approaches is necessarily right or wrong. The best choice depends on your budget and what you're looking to learn about your cycle.
