If you’re looking for a hormone-free, more natural form of birth control, then you might want to consider the NaturalCycles fertility app as an option. (I swear there’s an app for everything.)
The only thing is you need to know what you’re doing or you’ll end up giving birth instead.
The app requires two bits of data: your basal temperature and the results from an ovulation test before it can accurately tell you when it’s safe to have sex.
The basal temperature can be tricky if you don’t record it as soon as you open your eyes in the morning or if you’ve had a few cocktails the night before. (Drinking skews the results.) Also, you kinda already need to know when you’re ovulating so you know when to take the ovulation test.
Oh, and then there’s the $60 annual cost to use the app.
But remember, it’s 100 percent natural and 99.9 percent proven (sounds like a paternity test) to work if you input the right information.
Just keep in mind, NaturalCycles only prevents pregnancy; it doesn’t protect against STIs.
