I am using the clearview ovulation test. Nowhere in the paperwork did it indicate you could not use the test after receiving the smiley. I had gotten low for two days, and then a smiley yesterday. Today the screen was frozen on the smiley and nothing could change it. It was like it was frozen. I tried taking the back off to reset the battery, and after that it only displayed the book symbol. It makes me really unhappy to have paid so much for a product I could only use 3 times, and am not sure is actually even working.... What should be done in this instance??
