Nope!! I tries using them when we started TTC and was thrilled to see dark positives straight away. Every few days was the same though, I had more positives than negatives, and ALWAYS a decent line...don't trust them at all. I think temping is a good choice. I didn't manage a single decent chart in my 3 months TTC but I'm a terrible sleeper which I think had an effect! Are you on Clomid?
