I actually ended buying only a few from my local dollar tree store only because I gave all of my opks (more than 50+ wondfo opks + wondfo hpt's+ frer's :((**) and everything I had bought for ttc to a coworker because I was fed up and I didn't want to ttc anymore. They are called New Choice Ovulation Predictor compare to Clearblue. The reason was because this whole ttc and swaying took a toll on me and I was tired of not getting pregnant. I did temp from September 2013 to May 2014 and i just stopped doing it. I was hardly getting any sleep as it was and having to wake up at the exact time and temp made me loose my mind lol.
