Correct answer: A — Fertility awareness is less reliable with irregular cycles

Fertility awareness methods depend on recognising fertile windows and are less reliable with irregular cycles or when biomarkers are difficult to interpret. Apps alone may not provide robust contraception. If pregnancy avoidance is important, more effective methods should be discussed.
