This device is not intended to be used as a contraceptive or pregnancy test, nor is it proven to provide any definitive information during pregnancy. Use only as a means to monitor your most fertile stage.
It’s usually not recommended to use ovulation tests as birth control because ovulation predictor kits (OPKs) only identify the most fertile window (up to 72 hours), and sperm can survive in the body up to 5 days.
