Most Common Issues People Have with Fertility Monitors

  • Inaccurate Results: Fertility monitors are just tools to help you know whether or not you are pregnant. Sometimes, tools don’t work as well as expected. Different types and qualities of testing are present with different fertility monitors and not everyone chooses the monitor which gives the most accurate results.
  • One-Time Testing: Many fertility monitors are designed to be disposed of after only one use. If you are serious about having a baby, this can quickly become inconvenient. If you don’t want to buy new fertility monitors after each test, one-time testing kits shouldn’t be your top choice.
  • Minimal Data Results: Many people are not only interested in the fact that they are pregnant, but also want further data. It is common for people to not understand that fertility monitors can come with much more than a positive or negative result and simply purchase a cheap model with minimal data.

Important Tips

When shopping for a fertility monitor, you want to make sure you purchase something that’s reliable. You don’t want to gamble and get a device that doesn’t work properly especially when you are trying to avoid pregnancy. So, to give you a head start, here are some key factors you should consider:

Type of Monitor

While all fertility monitors serve the same purpose, they differ greatly when it comes to the methods used to measure and predict fertility.

They are designed to track either hormonal changes, basal body temperature or electrical resistance of saliva as well as vaginal fluids. There are some other models that utilize a combination of these methods.

Hormone Level Detecting

This is the most common method utilized by fertility monitors. In this case, the monitors work by measuring and analyzing changes in the levels of fertility hormones in your body.

You will find monitors that track only the luteinizing hormone LH which is the defining standard as far as determining your fertility is concerned.

On the other hand, there are some models that track both the LH and estrogen hormone such as the Clearblue fertility monitor.  This means that they are able to accurately pinpoint your fertile period. Therefore, the best option here is to go with a unit that measures both hormones so as to get precise results throughout.

Basal Body Temperature

There are many other fertility monitors that rely only on tracking changes in body temperature. Through analyzing your BBT, these monitors are capable of producing pretty accurate results to help you figure out your menstrual and ovulation cycle patterns.

Most BBT trackers use a thermometer to capture the readings and as such the measurements have to be taken immediately when you wake up. There are some models that use sensors incorporated in a skin patch to track and analyze your BBT throughout the night as you are sleeping.

These devices record and analyze your body temperature so many times overnight hence are able to deliver a far more accurate prediction of ovulation. In general, the key thing to consider when purchasing a BBT fertility monitor is how often the device takes measurements.

The more frequent it is, the more reliable results you will get. A good example here is the iFertracker fertility monitor.

Electrolyte Levels

Another recognized way of determining fertility is through tracking changes in the electrolyte levels of saliva and as well cervical mucus. Here, most monitors use an oral and a vaginal sensor to measure this changes upon which they are able to pinpoint your most fertile period.

Generally, personal preference will play a major role in the type of monitor you will choose. If you want non-invasive method then BBT monitors with patches are much more ideal. But if you don’t mind using test sticks or invasive methods, then you can go with hormone-level detecting monitors.


Best Fertility MonitorsWhether you intend to get pregnant or want to avoid it, accuracy should be your top priority. While you are not going to find any fertility monitor that’s 100% accurate, you want to make sure that you select one that has a pretty high accuracy rate. You should consider fertility monitors that have an accuracy of 97% at the very least. The higher it is the more precise results you will get from the monitor which help you to plan accordingly.

Considering that sperm can survive for more than five days in the body, it’s also important that you consider a unit that can identify a much longer fertility period, preferably more than 6 days. This will ensure that you have optimum chance of getting pregnant if you want a baby or, want to avoid it in the long run.

Ease of Use

The goal of a fertility monitor is to facilitate a hassle-free way of determining whether you are fertile or not. Therefore, it needs to be easy to use and deliver results that are easy to read and understand.

There are monitors that come with display screens while others have color-coded indicators. There are also some models that require the use of a smartphone in order to view the results. The former is much better as you will be able to view the result right there without the need for an app.

However, either option can be good depending on your preference, but most importantly ensure that the monitor you will choose can record and analyze your data after every test. Doing so means that you will have a monitor that will be able to quickly get well acquainted with your system and as such be in a better position to deliver more accurate predictions.

Serious Buying Decision
