Disclaimer: Sex makes babies. It’s pretty straight forward. Obviously, the only fail-safe method to prevent making babies is not having sex. But that sounds horrible. So, when you do have sex, we strongly recommend you do your research and use whatever form of prevention works best for you.

Our pregnancy forecasting is dependent on several factors: cycle length, period duration, ovulation during your cycle, and you being intelligent. Please put correct dates into the Aunt Flo Period Tracker so we can best forecast your cycle. Anxiety, stress, mood swings are all normal, cus you're a woman. But they do affect your cycle. Diet, nutrition, exercise, medications, age and many other factors can also affect your cycle month-to-month. Aunt Flo is here to help with what we can, but hell, we can’t do everything for you!

Exactly what I needed

POTC luva <3

I don't understand why there are so many bad reviews I love this thing. I've been using it so far the past couple of months and haven't had any problems with being logged out. It's exactly what I needed: a simple app that will help me remember when my cycles are and makes it fun to do so because I hate my period and keeping track of its history. Good laughs and my friends love it too! Hopefully it continues to work well. And to all the women saying "waste of money"... is donating to a good cause really a waste to you?



I hate Mother Nature, but this app makes it easier than ever. There were a few glitches when I first started using this app, but the support team was always helpful in resolving them and they’ve made this app better over time. It’s simple and it’s not trying to convince me my period is about rainbows and butterflies. I love the design and it’s super user-friendly. I’ve recommended this app to a bunch of my girlfriends and they all love it! Definitely give it a try—you won’t regret it. 💕



I don't want to pay for an app and then have to predict what day my period is about to start
The whole Point for me was to have it automatically calculate because I may forget to jot it down. I'm normally off and on the road for work travel and this becomes frustrating. I've had the same problem 4 times now that when I click on here it's blank it doesn't say anything. It doesn't have my last cycle stored or anything. My last month's calendar is blank as well and my profile picture is gone. Come on! Ugh I'll download another one for backup but this app shouldn't have a price on it at All.
