Timing of IUI

Sarah

I'm going crazy about the timing of my <a href="https://glowing.com/glow-fertility-program">IUI</a>. Doing an unmedicated cycle with FDS. I am using Wondfos and backing up with CBD. This morning I got a flashing smiley (high) and my Wondfo isn't positive. My partner bought the 4 day CBD and I think this might make things more confusing. My OB wants me to call the day of my positive and then go in the next day for my <a href="https://glowing.com/glow-fertility-program">IUI</a>. What is considered the positive? The high, or peak? Makes sense to me that it would be considered the peak or else it would be too early. I've also had really good luck with the Wondfos and previous months. They tend to line up best with Glow, my CM and other O signs. Any advice or experience appreciated!!
