Best Ovulation Predictor Kits (OPKs)

The key with OPKs (ovulation prediction kits) other than reading the instructions carefully, is to know a line on the test doesn’t equate to a positive reading. A positive reading is generally when the test line is as dark as or darker than the control line. On top of that, a positive reading means your body is gearing up to ovulate within the next 12-48 hours. Sometimes the lines on even the best OPKs can be hard to read, so many women back them up with a digital, or skip the frustration and go with the big daddy of ovulation predictors: a fertility monitor.
