It works!

Due to a history of irregular menses as a very athletic 18 year-old cross country runner, I was put on The Pill to regulate my periods for 14 years straight. Years later, my follow up lab work with an endocrinologist cleared me from any hormonal problems. At age 32 I stopped taking The Pill, and my periods were "regular", but 36 day cycles. Nonetheless, I used this app to track my periods & symptoms. I got pregnant during month # 2! Who knows how accurate it is but it seemed to work.
