LH strips and cycle-tracking apps are often marketed as tools for understanding fertility — but they are increasingly being misused as a form of contraception, with real consequences.

In this episode of FERN Rising, Dr. Ashley Burton explains why LH ovulation strips are not a reliable or safe method for preventing pregnancy. Using real clinical experience and reproductive physiology, she breaks down what LH strips actually measure, why they do not confirm ovulation, and why they cannot define “safe days.” This episode also addresses why LH strips are especially unreliable for women with PCOS, where frequent or elevated LH surges can occur without ovulation.

You’ll learn why apps and LH strips lack the cross-checking required for fertility awareness, how misunderstandings about cervical mucus lead to accidental pregnancies, and why so-called “non-peak” fertile mucus is not safer than peak mucus. Dr. Burton also explains sperm survival, why every cycle must be evaluated on its own, and what distinguishes true fertility awareness methods from guesswork.

This episode is essential listening for anyone using — or considering using — fertility awareness for contraception, and for women who want body literacy rooted in physiology, not assumptions.
