Has your cycle been affected by COVID-19 infection or vaccination? Tracking your period volume, pain symptoms, and cycle length in Clue can help you to understand if and how you’ve been affected.
We’ve seen plenty of anecdotal evidence flying around social media about how a COVID-19 infection or vaccination can disrupt the menstrual cycle – whether it’s heavy periods, late periods, or even periods returning after menopause. These claims are yet to be verified by scientific research, but expert Kathryn B. H. Clancy, PhD at University of Illinois, says that any changes shouldn’t last longer than a cycle or two.
As the science evolves, we will continue to update our website (www.helloclue.com) with evidence-based research about any possible link between COVID-19 and the cycle.
This update includes bug fixes and behind-the-scenes work to keep your tracking as accurate and seamless as possible. If you're enjoying using Clue, feel free to leave us a rating and review!

Ratings and Reviews
Amazing App!!! (And suggestion)
This app is AWESOME! Periods, ovulation, pregnancy, and other things like that are SOOOO confusing (obvi) but Clue breaks things down so its easier to understand, which is really useful. And it’s NOT one of those apps that pretends that periods are the same for every person. When you enter something, it recommends articles and other things for you based on what you put in. I just want to say that this app is really useful, and well put together. It’s made by women, so it makes you feel like you’re not alone. And I have a VERY unpredictable cycle and it’s almost always spot on! And if you are taking hormonal birth control, it has options for lighter or no periods. I do have one recommendation for the app, there’s a section that asks what kind of birth control you use, right now, I don’t “have a need for birth control yet”, if you know what i mean, so I think there should be an option for that. Also they’ve started using gender neutral language in their app and even have articles on tips for gender dysphoria on your period, effects of getting testosterone, pregnancy when you’re non binary, pros and cons of daily Binding, and more. A very good, science-based, inclusive app! I would recommend for anyone with a cycle! Edit: one bug I’ve noticed recently is they have like notifications in the app for article recommendations and it’ll have the little red circle and I’ll swipe up and it’ll say ‘no new notifications’

More than anticipated
I got clue because I was having a difficult time remembering to track my period on my messy calendar. When I began using it, I found that it was very easy and straightforward to use with customizable tracking options besides just the period bleeding itself like emotional state, pain, ovulation, sleep, digestion, etc. I just wish that the exercise tab had more options to choose from. After using it for a few months, the app had enough data to show me patterns during my cycle which were very enlightening to me. By recording my daily experiences and looking at the generated patterns and predictions I have been learning a lot about my body that I was previously unaware of before. But my favorite thing about discovering clue is that the company provides articles on women’s reproductive health for free on many different issues, and that these articles are fact-checked and use peer-reviewed journal studies as their sources (and list the sources so I could look them up myself if I wanted to). These articles provide me with information I otherwise didn’t have access too or was too embarrassed to ask about like the many birth control options available, how they work, and their pros and cons. Definitely more than just a period tracking app.
This app is literally the best period tracker I’ve ever had. I started using it just over a year ago(ish), and it’s truly been helpful. I added in my past periods from another app and that helped a lot with it being able to always be spot on for my days.
One thing I would recommend, is having a “Notes” section for days. I feel like that would be nice because I can remember why I didn’t take my BC (birth control) at a certain time and I can work on being more on time with it. It’d also be nice to keep track of other things in there, such as “my cramps were this bad today because xyz.” And instead of using just the cramps button, I can make a note of how bad or mild they were on which days so I can expect it for next time. I also feel as if it would be easier when talking to an OB/GYN about my periods because my cramps can sometimes be too horrible to the point I can’t even get up and out of bed (the top reason why I’m even taking it - and how irregular my cycle was before).
A couple months ago I got the subscription to Clue, and it’s even better than I imagined! I enjoy getting the articles for what I feel on my period; certain emotions, why my cramps can be killer, etc. I’d definitely recommend this app to all my fellow friends. 💕
