First Response Ovulation Kit 7+1 Tests
Maximise your chances of becoming pregnant. Predict your 2 most fertile days in the month with the First Response Pregnancy Planning Kit. The First Response Ovulation Predictor Test detects the LH surge, which precedes ovulation by 24-36 hours. Your two most fertile days begin with the LH surge. If you have intercourse within the next 24-36 hours, you will maximise your chances of becoming pregnant. There is no need to wait until you ovulate before having intercourse.
