We’ve all heard the phrase “the pill is only 99% effective“, but what does that mean? Over what time period? And at what age? Believe it or not, the time period is actually one whole year… but trust me, it gets more complicated than that… That’s why we made the free pregnancy chance on The Pill calculator:

How Our Pregnancy Chance Calculator Works
Our Pregnancy Chance Calculator allows you to estimate your pregnancy chances based on over 20 of the most common contraceptives, including the pill, IUDs, implants, condoms, and more. You can also use the calculator to estimate your chances without any contraceptive method.
When it comes to the pill, the calculator takes into account how consistently you’ve been taking your pills, your age, and how often you’ve had intercourse during the period you want to assess. This provides you with a personalized estimate of your pregnancy risk, helping you make informed decisions.
