Predicting ovulation doesn’t take mind-reading abilities. Simple observation and a few ovulation predictor kits (OPKs) from the pharmacy are all you need to pinpoint the big day. OPKs determine the rise in luteinizing hormone (LH) that occurs just before egg release. Your partner urinates into a cup, dips the test stick into the urine, and reads the results.

The only drawback to OPKs is that women who have high levels of LH normally, like women in or near menopause and women with PCOS, may not get accurate results.
