Clomid and Ovulation Predictor Tests

I finished my first round of clomid a few days ago, 50 mg. I didn't have a singal side effect. I was pleasantly surprised. I had braced myself for the worst, hot flashes, moodiness, morning sickness, I was ready for it all, and nothing. I feel very fortunate.
Yesterday I did my first Ovulation test, it looked positive to me. I don't know if they work though, because today's was definately negative. We'll see if my temperature goes up tomorrow, then I'll believe that the test strip told the truth.
