Natural Cycles places birth control into your own hands.

Founded by particle physicist, Dr. Elina Berglund, with a goal to offer women an effective, hormone-free method of birth control, Natural Cycles identifies ovulation by analyzing basal body temperature, learning your unique cycle so you can get to know your body better, and know the exact days you can and can't get pregnant.

Natural Cycles is a clinically-proven birth control option alongside the pill, IUD and the condom. 93% effective with typical use, and 98% effective with perfect use. The clinical study that determined Natural Cycles' effectiveness is one of the largest of its kind, with 15,000 women and 600,000 menstrual cycles. It was peer reviewed and published in the renowned journal Contraception.*
