hehe I think it's pretty cool. They are not available here, so I ordered mine from the USA.

I am not sure on the rules about link posting so if this has to be removed let me know OV Watch | Ovulation Predictor, Fertility Monitor, Ovulation Kit, Trying to Get Pregnant

I am on CD20 now and it predicted my ovulation and the 4 fertile days before. So fingers crossed it will work for us this month!
