When a woman can’t get pregnant and it’s not clear why, sometimes doctors recommend fertility monitors or ovulation kits that determine whether or not she is ovulating and detects the best days in which to become fertile.

Some fertility tests are known as the Clear Blue Easy Fertility Monitor and the Ovu-Kit test kit.  Such kits are vital in situations of infertility but can be used by healthy couples to determine the best days to get pregnant.

The Clear Blue Easy Fertility Monitor is simple to read and allows a couple to determine their six most fertile days of pregnancy.  It is a urine test that is put into a reader and the reader determines the levels of both estrogen and luteinizing hormone in the urine.  Estrogen rises first, just before the luteinizing hormone rises and this is determined in a Clear Blue Easy Fertility Monitor.

Following the estrogen rise, the luteinizing hormone rises, signaling the advent of ovulation and the most fertile days of the cycle.  The Clear Blue Easy Fertility Monitor tells you when the luteinizing hormone surge is happening.  These six days are the days one should have sex to achieve a pregnancy.

The Clear Blue Easy Digital Ovulation Test kit is another product by the same company and detects only the luteinizing hormone (LH) surge that occurs 24-36 hours before ovulation and predicts the best two days to get pregnant in any given cycle.  It is digital so you don’t have to read a strip or pay attention to a color change, which makes it easier to tell which days are detecting the LH surge.

The test is used once a day at the same time of the day on the days you expect that you might be ovulating.  Such a test is 99 percent accurate in detecting the LH surge.  Results show up in about three minutes.

The Clear Blue Easy Ovulation Test Kit is a nondigital test kit that otherwise operates similarly to the digital kit.  There are seven test sticks that are included in the kit and you begin testing about four days before you expect to ovulate.  For those who have long or irregular cycles, more than one kit may be necessary and you start testing at around day ten.

The test determines the luteinizing hormone surge and a color change with lines to read are used to determine when the LH surge has occurred.  Ovulation follows in 24 to 36 hours later.  Such a test is about 99 percent accurate in determining the LH surge.

The OvuKit test kit is more expensive (about $50) than other kits but it is considered by many fertility specialists to be more accurate than other kits.  It detects the LH surge and is available in five day and 9 day test kits.  The nine day test kit is designed for those who have long or irregular cycles and is based on a color change on a stick.

Ovulation test kits are an excellent way to determine when to get pregnant and are usually very accurate.   If you don’t detect an ovulation on these types of kits, you may not be ovulating and you may need to have a consultation with a fertility specialist.
