5 Popular Fertility Monitors: Which One is Right for You?

This post contains affiliate links.  You can see my full disclosure here.


I don’t know about you, but I’m so grateful that we live in a time when we have so much technology to help us in our fertility journey.

Think about it… we are the first generation whose family-building efforts have been assisted by apps, monitors, home test kits, and reliable medical information online.

Lately I’ve seen lot of ads and reviews for different fertility monitors.  I wondered if they’re really worth the extra money.  (After all, those trusty Wondfos and other basic ovulation test strips are pretty cheap). What makes them so special and what differentiates one from the other?

So I decided to do a comparison of five of the most popular fertility monitors and share them here with you.  I hope you find it helpful if you’re interested using one.

Ovusense Real Time Fertility Monitor


This overnight monitor is worn internally (yes, up there).  It claims to provide a day’s notice of ovulation in real-time and a 4-day ovulation window with 99% accuracy.  It syncs with your iPhone or Android and is recommended for women with PCOS.  It requires a subscription (there are several different price points) and is approved for sale by the FDA*  in the United States.  If you want a detailed review, check out my friend Elisha’s hilarious (and informative) review.

Available for $99-$345 on Ovusense’s website.  Ovusense will extend a special discount to my readers.  Simply send an email to support@ovusense.com and mention Amateur Nester blog.  

OvaCue Mobile Fertility Monitor



This monitor consists of an internal sensor (yup, another one you put up there) AND an oral/saliva sensor that you use each day, within the recommended 2-hour testing window.  It syncs up with an app you can use on your iOS device (or select Android devices) it and will store your cycle information for up to four months.  It does not require any subscription fees or test strips, so it saves you money in the long-run and it’s better for the environment.  It claims to predict ovulation up to 5-7 days in advance with 98% accuracy, and the manufacturers say it will work for women with irregular cycles and PCOS.  An added benefit is that OvaCue specialists at FairHaven Health are available to help you make sense of your results and charts.  How cool is that?!  If you want to see more pics, check out the brief review I did in 2015.

ClearBlue Fertility Monitor

Unlike the other two monitors I’ve mentioned so far, the ClearBlue Fertility Monitor is a stand-alone model; it doesn’t sync with a mobile device. And for those of you who were turned off the by internal sensors of the other monitors, you’ll be happy to know the ClearBlue Fertility Monitor doesn’t require you to insert anything into your body! It reads urine test sticks (purchased separately) and detects both the LH and estrogen (it’s the only non-invasive monitor that does this) to help determine your 6-day fertile window. The touch-screen monitor stores up to 6 months of information and is appropriate for women with cycles of 21-42 days. It claims to be 99% accurate in predicting the LH surge (which is an indicator of ovulation).

Monitor available on Amazon for $101.   Urine test sticks are $37.  

Ava Ovulation Tracking Bracelet 


The Ava is definitely unique in that it’s a bracelet!  If you’re someone who might have trouble remembering to test at a certain time and doesn’t want anything to do with pee sticks or internal sensors, the Ava might be an option for you.  You wear it at night and sync it with your iPhone or Android in the morning.  It claims to use your resting pulse rate, along with some other physiological indicators, to determine your 5-day fertile window with 89% accuracy.  This FDA-registered* device also tracks your sleep and stress levels.  The Ava is best for women with regular cycles between 24-35 days, and it has not been tested for women with PCOS.  Note: A close friend of mine ordered this and was so put-off by the long wait for it to be shipped that she eventually canceled the order.  Their own website says it takes 3-4 weeks to ship.

Bracelet available on AvaWomen for $199.  

KNOWHEN Advanced Ovulation Kit


If the idea of spending over $100 on ovulation-tracking doesn’t sit well with you, the FDA-cleared* KNOWHEN Advanced Ovulation Kit might be a good “in-between” choice for you.  At a price range of $50-$75, it claims to pinpoint your 5-day fertile window with 98.9% accuracy.  It works by letting you look closer at a drop of saliva (almost like a microscope) first thing in the morning to determine your level of fertility.  It’s perfect for your inner science-geek!  No test strips or internal sensors required.


Available on KNOWHEN’s website for $49.99.  They’re also running a promo that gives you a $10 VISA Gift Card when you download and register and app that is included in the kit.  Use code AMN01.  There’s also a deluxe version available on Amazon for $75.  (Promo not available on Amazon).

Resisting Bitterness During Infertility


When we were trying for our first child, fear and sadness were the emotions I felt the most.

I was scared it wouldn’t work and that I’d end up childless and broke.

Now we have our miracle daughter, and the fear is gone.  Yes, we deeply want another child,  but I know how lucky we are to have even one, and we will be more than content even if we only have her.

So now I’m not scared.  I’m not sad.  I’m just angry.

SO. FLIPPIN. ANGRY. about doing IVF again.  Yes, frozen cycles are way easier than fresh cycles.  But I’m angry that now I have to decide between a medicated transfer cycle and a natural transfer cycle.


We love our current RE.  His office is 10 minutes from where we live, and we received excellent care from him.  But he only does medicated cycles; he won’t do a natural cycle.

And guys, the thought of more Lupron, more Estrace, more heparin, and more prednisone literally makes my heart pound with anxiety.  I’ve contacted Stanford Fertility to see about scheduling a consultation with them for a natural FET cycle.

It really ticks me off that I have to do this.  I thought I’d come to terms with having to use reproductive technology to get pregnant, but apparently I haven’t.  For about two days last month, I thought I might have been pregnant naturally, and I was so angry when I wasn’t.

So, my prayer in these upcoming months as we make our decision about a medicated FET vs. natural FET is that I would not fall into a pattern of anger and bitterness.

Like the quote says, “Bitterness is believing God got it wrong.”  And I do not believe for an instant that God got my fertility journey wrong.


Oh, it definitely wasn’t the way I would have planned it.  But I can honestly say I wouldn’t change anything.  It led to my daughter and to so many other beautiful, rich things in my marriage, my faith, and even this blog!

Lord, help me (and all my infertility sisters) to look to you to for the strength, hope, and courage we need to keep our anger from turning into bitterness!

Courtney’s IVF Story

Today’s post is a guest post from Courtney.  I decided to share it because I know that a lot of you struggle with whether or not you should pursue IVF.  I think that’s a very valid struggle (and IVF is not for everyone).  I thought it might be helpful and encouraging to any of you in the same situation.  

My name is Courtney and my husband is JJ. We are parents to a 6-month-old named Noah who we conceived via IVF after almost two years of infertility. We were married in 2013 and started trying to conceive about nine months later.

ivf story

After a year of not getting pregnant, I went to my doctor and he agreed something was wrong. He ran some tests on both my husband and I, and started me on Clomid. My lab work came back extremely abnormal, I had some issues on Clomid, and shortly after we were referred to a local reproductive endocrinologist. We tried five total medicated cycles with both oral and injectable medications and a medicated IUI before our RE sat us down and told us our only option was IVF.

We had always talked about the possibility of doing IVF but I never thought it would actually come to that. We had been somewhat private about our struggles with infertility and had spent too much time looking for support in the wrong places and validation in choosing infertility treatment from people who didn’t understand it. Before making a decision about what to do, we prayed and talked about it with some of our best friends. Doors we thought were previously closed opened and we decided to proceed.

ivf story

In February 2016, I had 33 eggs retrieved, most of which fertilized, and three survived to Day 5 embryos. We did a fresh transfer and found out two weeks later we were pregnant. Noah was born in October 2016.

Infertility was the darkest and most isolating road I have ever walked. I was in such a bad and dissociative state of mind I can barely remember parts of our journey except how much they hurt. My husband is seven years older than me and most of our friends had kids. I’m a pediatric nurse and we were the only couple at the time at our church without kids. At the time, I knew very few people who had gone through it and couldn’t relate well to anyone. Our infertility was solely female factor and I had (and sometimes still have) a very hard time with that and the shame and guilt was all consuming.

ivf story

My lowest of lows came when our last medicated cycle failed. Everything had looked perfect and I had been so sure it had worked, I was such a mess I could barely get out the door and go to work. I called someone to talk about it and the conversation made them so uncomfortable they basically hung up on me.

Over a year later and I am very open about our struggle through infertility and IVF. It took a long time to get to the point of sharing our story but it has been a wonderful blessing for us. I have met and been connected to some incredible people who have been down the same road and have been a resource for people who are just beginning their journey. I know now that taking a leap of faith and pursuing IVF was part of God’s plan for us to be Noah’s parents.

Many thanks to Courtney for sharing her IVF story.  Please leave her a comment to let her know you appreciate her!
