Abstention or protection (e.g. condoms) are required on red days to prevent pregnancies. ○ As a birth control, Natural Cycles may be less suitable if you experience irregular menstrual cycles as predicting your fertile days becomes more difficult and you will get an increased number of red days.

  • Get to really understand your cycle with this fantastic app.

    By ToughTinyMomma
    This app is fantastic. It does it all from tracking your cycle to warning you "you should start your period next week you may experience some PMS now" to helping you keep track of sexual activity and really become more aware of your body through keeping track of the cycle of change we women go through so frequently! My nutritionist recommended this app to me and I recommend this to everyone who is a candidate for it. It is very easy to use and you can at anytime switch the option on your profile from trying not to get pregnant to trying to conceive so this app can follow you down the different paths you choose to take with your body. So so happy I found this app and am now more in charge and aware of my own body!
  • Impressed! Never turning back

    By bellaeclisse
    I am so impressed with how easy and user-friendly this app is! I was a Kindara user before but that required me to take the time to learn about the fertility method and, though I do plan on diving into fertility education, honestly I needed something easier and quicker! This app is amazing, you’re able to plan in advance when you will be fertile or not, and all it requires is a BBT. After your temperature, it literally does all of the work for you! This is great for people with busy lifestyles who need a quick answer!
  • Hormone free, stress free

    By bigsley!
    I’ve been using NC to prevent a pregnancy for 9 months now and I’m absolutely thrilled with all the benefits. It’s not only a successful contraception method, it’s a great way to know your body and understand your cycle!! Very informative and educational. They customer care is also great!!!
  • Every menstruating woman needs this

    By BirdieSoph
    Was on the pill for 7 years - age 15 to 22. High blood pressure forced me to switch from the combination pill to the mini pill, but with that came other horrible side effects: headaches, moodiness, and just feeling down for no apparent reason (I’m not susceptible to depression at all). This led me to research other birth control options, and in my search I found that the pill is horrible for your body. Scared me so bad I stopped taking the pill immediately and found this app to use as contraception. I’ve completed my first cycle on the app and I am absolutely loving it. I will never look back.
  • Pregnant while using this as BC

    By Tabinlovewithninjawarrior
    This did work for a few months, and I believe if it weren’t for user error it may have continued to work. Unfortunately I had a cold that lasted about a month, and I think that threw my nasal temp off enough to mess things up. Always err on the side of caution and mark your temp as deviating if you’re the least bit unsure.
  • Very helpful

    By Cheyenne Les
    I am currently using this to prevent pregnancy and not use hormones. It’s pretty great it accurately detects ovulation and has slot of Green Day’s. My only complaint is it still after three cycles wants to predict my ovulation day as the average which is Cd 17. But I’ve been tracking for a long time and I know my ovulation is between CD 13-15 never earlier never later. And I’ve tried to input that into the prediction and it still wants to put mine as average ovulation only after the shift in temp it changes it to the correct date. This I feel would be a problem for someone else who did not know their cycle like I do.
  • Wow

    By Tish Douzart
    Ok, strange confession here (maybe not so strange?): I’ve never used hormonal birth control. I begged my mother when I was a teen because I had awful, painful periods. She wouldn’t do it. By the time I was in college, I just didn’t want to alter my hormones; I’d heard and read too much about side effects and long term use reactions. So I never took up the pill. I’ve always used the rhythm method. I’m 41 now and when I came across this app, I decided to give it a shot. I’ve been using it for 5 months now and it is amazing! It’s crazy how accurate it’s predicted the first day of menstruation ON THE DOT, each time! The app even told me that my body works like a clock...LOL! It’s empowering to know how your cycle is playing out and even though I’ve been pretty in tune to my body’s calendar, this really sets a lot of occasional anxiety at ease. Highly recommend!
