There are no additional costs for supplies. It is a one-time purchase. Unlike chemical birth control devices, the LFI is completely natural and does not interfere with the body's natural processes. In fact before you set up anappointment with a fertility specialist you can use the LFI to determine what your cycle looks like. Fertility cycles average 28 days, but can range from 23 to 40 days.
Ovulation can even occur twice in the same cycle.
By using the LFI every morning and plotting the results on the fertility chart, you will know exactly what stage you are at. You can use these results to aid your doctor and determine any irregularities in your cycle. For best results, you should use the LFI first thing in the morning prior to brushing your teeth or drinking juice, etc. Do not consume any water, alcohol, sugars, food or cigarettes for at least 2 hours prior to taking the test. Your test results will be affected causing false positives.
