Is there a way to check whether ovulation has occurred?

Literal

Ovulation [possessive-の] presence-or-absence [object-を] investigate method [topic-は] exist [question-か]?

A practical health question. 排卵 (ovulation) is a medical term. 有無 (presence or absence) is a compact formal compound from 有 (exist) + 無 (not exist). ~方法はありますか is the standard 'is there a method to do X?' pattern.
