After my first miscarriage, I became obsessed with getting pregnant again, and spent a lot of time on various miscarriage/ttc forums.  I’d waited two months to allow my body to recover, and when I was ready to try again, I wanted to increase the chances of getting pregnant right away.  Many of the women on the forums were experts at tracking their cycles by charting their basal body temperature, checking their cervical mucus, and being attuned to their cycles.  They knew exactly when they ovulated and what days they were most likely to conceive.

I’m an obsessive person, but I’m also a lazy person.  So when I read about the ClearBlue Easy Fertility Monitor, I knew that I wanted to give it a try first.  The Fertility Monitor detects your high and peak fertility days with 99% accuracy.  Since you can only conceive a couple of days a month, you want to know which days you’re most likely to get pregnant.   I’d already had a good friend as a guinea pig — after trying to get pregnant for 6 months unsuccessfully, I suggested she try the ClearBlue Easy Fertility Monitor, and she got pregnant that month.  I was sold.

Here’s how it works. The following chart shows an average woman’s menstrual cycle.  Her two most fertile days are 24-36 hours before ovulation, and the day of ovulation, which the Fertility Monitor detects by the presence of the luteinizing hormone.  But because sperm can live inside the female body for up to 5 days, it also tracks the 5 high fertility days prior to ovulation by detecting the rising estrogen in your system.  So if you do the baby dance on your most fertile days, you’ve optimized your chances of getting pregnant that month.

Here’s how the monitor works.  You set it to the first day of your cycle and turn it on each day.  It’ll tell you when to start using the test sticks, at which time you’ll pee on a test stick first thing in the morning when the concentration of your hormones is the highest.  Then place the stick inside the monitor, and you’ll have a result in 5 minutes.


The monitor isn’t cheap — a starter kit that includes the monitor, 3 months of test sticks, and 3 home pregnancy tests costs $290.

Although the monitor didn’t help me get pregnant, it did help me identify that I wasn’t ovulating at all.  Otherwise I may have tried to conceive for months before going to see my doctor.  So for that, I’m very thankful.

Have you tried the Clearblue Easy Fertility Monitor?  Would you ever try using such a monitor?
