Question - Clomid/Ovidrel before IUI

I did Clomid this cycle, triggered this morning with Ovidrel and will have my IUI tomorrow. This morning when woke up I had really watery CM. Took an ovulation test, negative. So I went about with my trigger and didn't think anything else. Throughout the day the watery CM has gotten worse. No EWCM like I'm ovulating. Just watery. I am wondering if anyone else had experienced this with a similar cycle? I am just worried I am going to miss my window.
