I bought two boxes of this product and freaked out and thought I was not ovulating because I used them as directed and they did not pick up my LH. On the days I was ovulating, the tests showed a very faint faint line...which means Negative. I went to a fertility endocrinologist and had testing done and it turns out I'm FINE! No problems with LH or anything else. Ordered tests in just the plain strips from Amazon. They are called Babi. My Dr. reccomended the plain strip with no casing (like the 7 day first response for instance). Don't buy this. Waste of time and money.
