If you are having difficulty becoming pregnant, it could be that you are not making love in the 2 days when you are most fertile, around the time of ovulation. First Response Ovulation Test will help you identify these days by detecting the rapid increase in luteinising hormone (LH surge) which normally occurs 24-36 hours before ovulation. Your 2 most fertile days begin with the LH surge. You are most likely to become pregnant if you make love within 36 hours after detecting your LH surge

† Based on directions of use
*** Over 99% accurate in detecting the LH surge in laboratory studies.
