Do you know what moment I absolutely hate? That inevitable part of any doctor’s appointment when they ask me the dreaded question: “When was your last period?” I expect to give out personal information, but I want it to be info I actually know!

As a PCOS patient, the likelihood that I can rattle off the dates of my previous period at any given moment is slim-to-none. My periods are so irregular, and it drives me crazy.

Yet somehow, despite knowing this topic is bound to come up, I always forget to have my answer prepared ahead of time. I’m left mumbling about irregularity and possible dates while the doctor looks at me as if I have two heads and zero clues about my reproductive system.

Thank goodness for period tracking apps that I can open so I have the exact data my doctor needs at the drop of a hat. And, you know, so I can understand my cycle, know my fertile days, or even get pill reminders for certain meds.

Thanks to the technological powerhouses that seem to run our world, there are several useful period apps women can use to keep track of their menstrual cycles and fertility.

Why is Finding the Best Period Apps Beneficial?

Before you jump into finding a period tracker online or start your search for the best free period tracker app, it’s a good idea to educate yourself on the benefits of tracking your period in the first place.

If you’re sitting there wondering, “Why should I track my period?”, there are a few great benefits  (including some that are quite surprising!)

(1) They Can Help Plan or Prevent Pregnancies

So, you’re not a birth control user, and you find condoms annoying – it might be time to start tracking your periods. If you want a baby, you can learn how to monitor your cycle. If you don’t want a baby, you can learn when not to have sex. Ovulation apps can help!

Tracking your periods can be used as a part of natural family planning and can help you pinpoint when you’re ovulating each month.

*Editorial note: We do NOT recommend period tracking as your sole means of birth control. We see many benefits to period tracking, but highly recommend additional methods of birth control if you’re tracking to avoid getting pregnant.

The average fertility window during any given month is approximately six days long. This window occurs before, during, and after ovulation.

By using period tracking apps, you’ll have a better idea when you will be ovulating so you know to either avoid doing the deed, or when to jump on it if you’re trying to conceive.

(2) They Can Help You Identify Potential Health Problems

When you start using one of the hundreds of different period apps available, they can help point out issues with your cycle, like irregularity or heavier-than-normal menstrual cycles. Either of these things, along with other “period problems” might indicate a more significant issue.

By using period tracking apps, you can better identify possible problems, such as PCOS, thyroid issues, and more, that need to be discussed with your healthcare providers.

(3) They Can Help Improve Your Sleep Cycles

Did you know that right before and after your period, your body temperature will experience a spike, and you’ll get less REM sleep than usual?

What this means is that you probably won’t feel as rested as usual.

By using a period tracker, you can identify when you’ll approach a phase of your cycle that can impact sleep. And take steps to help improve your sleep, such as limiting caffeine and not exercising too close to bedtime.

Find more information on creating good sleep habits and what to do if you can’t sleep due to anxiety or other causes.

Are Period Apps Accurate?

While a lot of time and planning has gone into creating period tracking apps, it’s essential to remember that 100% accuracy is not guaranteed.

These apps can help closely predict things like when you’ll ovulate or when your period will start, but it’s not an exact science.

For the best results, it’s crucial to find an app that’s carefully tailored to your unique needs. You should also keep in mind that outside factors like illness or extra stress can throw off your menstrual cycle.

The longer you use a period tracking app, the more accurate it will become. But if you’re using it to actively try to conceive, we recommend learning about the best ways to track ovulation.
