Clearnlue Fertility Monitor

Karen • Trying but not trying. If God wants us to have more children I’m open to it. Already had two mc. Our oldest is 17. Mostly now using it for tracking periods.
I am doing some research on this product. I would like to know if anyone here has used it, is using it. What your story is on it. 
I am TTC for almost three years. My husband and I had one mc early February. Doctor told us to take some time off. Which we did. Doctor also recommended for me to lose some weight which I am. Before I go back and go through expensive testing I want to see what other methods there are. So, if you could help it would be appropriated. Thanks!
