I have been using the clear blue fertility monitor, for a medicated cycle with Clomid 50mgs. All it did was show high fertility for days w/o a peak. I had all the signs of ovulation but no peak. Spoke with my RE and they have found that using that monitor is more often inaccurate and to use the OPK with the smiley face. Just want to save someone from the same frustration, waiting for their peak for <a href="https://glowing.com/glow-fertility-program">IUI</a>. I missed my window this month and I am very disappointed. At least I trusted my instincts and did the BD, during the time I knew I must be ovulating.
