false OPK results?

Morgan
I'm concerned about this mornings OPK results- they said the hormones were low. 
We triggered Friday night. I had ICI yesterday morning & am scheduled for <a href="https://glowing.com/glow-fertility-program">IUI</a> this morning. I forgot to take an OPK test yesterday morning. But now I'm wondering if my surge has come and gone already, if the test was faulty/I didn't get enough pee on it, or something else. 
Has anyone else experienced this? I do feel bloated & like things are happening post-trigger...
