Fertility tracker microscope

I've been collecting tips on tracking fertility, and it seems that most of my friends are somewhat suspicious of the high-tech methods, and go the calendar tracking route. If your cycle isn't clockwork regular, and harder to track, then ovulation predictors can help pinpoint your fertile days. Saliva testing (monitoring estrogen levels) is 97% accurate, and easier and cheaper than the urine Lh test kits. The Fertility Tracker is just 6" high, but the 100x microscope is twice as powerful as the more common lipstick-shaped predictors. The Tracker comes with six slides so you can compare your culture with slides from earlier days. The device is powered by two AA batteries, and is $39.95 at Babyhopes.
