A lot of couples may have been trying to conceive for an extended period without a result. It could simply be an issue of wrong timing. Many couples also do not know that they are only about 24 hours each month within which they can actually get pregnant. It is therefore important to identify the most fertile period of the month in order for the couple to plan intercourse. Identifying ovulation can be quite difficult especially if the woman has irregular period cycles. The BIOTEST Ovulation Test Kit detects the presence of Luteinizing Hormone in your urine. There are 3 kits in each box which allows the woman to find the most fertile day during her cycle. Some woman may need more kits compared to others. Once the LH surge is detected, this is the womans most fertile period for the next two days in the whole month and it is the right time to plan for conception.
