Has anyone used a fertility monitor?

Re: Has anyone used a fertility monitor?

I know..when i used the sticks the first time, it showed a smiley face and we didnt conceive then! Not sure whats happening! I guess its all up to Allah Tallah. I only bought the monitor because of the good reviews it got!

I wanted to find out if any of the guppies conceived by using it or anyone they know might have....
