Fertility Monitor?

I've seen the OV watch and works through a completely different mechanism than the standard urine monitors. I don't know of anyone that's actually used them, although the manufacturers say they're good, and guess have to go by what they say. I agree, if it truly works, must be alot easier. I wouldn't disagreed if you used the watch (if you do, let us know how it was for you so that others can see). Clear Blue Fertility Monitor is widely used like you said and know many patients who are happy with this.
